Spend more time talking and less time troubleshooting with this selection of top tips excerpted from Jeff Carlson's iChat AV 2 for Mac OS X: Visual QuickStart Guide. In just a few easy steps Jeff shows you how to build better buddy icons, save your chat transcripts, hook up to a Web cam, and solve those niggling problems that can make online chatting a chore.
Obtaining a Screen Name
To use iChat, you must have either an Apple .Mac (pronounced dot Mac) account or an AOL Instant Messenger (also known as AIM) account. Both services allow you to sign up for free screen names.
Apples .Mac is a subscription service that offers remote file storage, shared iCal calendars, online photo albums, and special software discounts and giveaways, as well as an iChat screen name. It also costs $100 per year. If you already subscribe to .Mac, use your mac.com email address (such as email@example.com) as your iChat identity.
However, if you arent currently a .Mac subscriber, and dont particularly want to shell out the $100, youre in luck. As of this writing, Apple is offering a free 60-day trial subscription to .Mac; if you decide not to pay for the full service, you still get to keep your .Mac address to use with iChat. Go to Apples Web site (www.mac.com/1/ichat.html) to sign up.
If you already have an AOL account, your screen name is also used as your iChat identity. If not, and youd prefer to use an AOL screen name, go to the AIM Web site (www.aim.com) to sign up for a free account.
Text Chat Etiquette
Although text chatting occurs in real time, its not the same as talking on the phone or in person. Here are some general rules and words of advice for when youre chatting with someone:
As with email, dont write in ALL CAPS. It gives the impression that youre SHOUTING.
iChat gives you the option of setting a default font and text size, but dont abuse it by setting your chat font to 24 point Arial Black. Other people see the font you choose, and though they can set their iChat preferences to format all incoming text, they shouldnt have to.
If someones status is set to Away, dont initiate a chat with them. I was (rightly) bawled out by a colleague for chatting while he was on a deadline once.
Its often better to post in bursts of a sentence or two, rather than composing a long paragraph of text before sending it off.
Because theres often a slight delay between posts, usually when someone is composing a response, its not unusual to have a few different topic threads going on at the same time. Sometimes it helps to introduce a new subtopic in parentheses. Then again, youll find that you pick up on multiple threads fairly easily once youre in the midst of them.
Making Better Buddy Icons
Apple has made it easy to add just about any image to iChat by performing the calculations required to shrink an image to a 32 by 32 pixel icon. However, the reduction process often makes images blurry, or sometimes doesnt zoom as close as youd like.
To make better buddy icons:
Zoom in. In iChat or an image editor, crop the photo tight around a persons face to show the most features. This also ensures you dont hit a zoom limit when using a larger photo.
Resize to fit. iChat uses two icon sizes: 64 by 64 pixels for the icon that appears in the Address Book application and iChats Get Info windows, and 32 by 32 pixels for the icon in iChats Buddy List. Rather than leave the resizing up to iChat, do the work yourself in an image editor so you know what youll end up with.
- Sharpen. Resizing an image tends to blur its details. After resizing your picture in an image editor, use its sharpening tools to bring back some details (Figure 1).
Note that if you import a 32 by 32 pixel version, youll need to use the zoom slider to zoom in on the icon to avoid seeing extra white space that appears.
* Tip Even if your source image is at a higher resolution, you need to save your icons at 72 dots per inch (dpi), or iChat will resample it for you.
Crop the image in an image editor such as iPhoto or Photoshop.
Resize the image to 32 by 32 pixels.
Sharpen the image.
Figure 1 Improve the appearance of your buddy icon by cropping the image, resizing it to match iChats measurements, and sharpening to bring out details.
Set the bandwidth limit
Open iChats preferences, and click the Video icon.
Choose a speed from the Bandwidth Limit popup menu. 100 Kbps (kilobits per second) is less capacity than 2 Mbps (megabits per second).
* Tip Changing the bandwidth limit is usually a good first troubleshooting step.
Working with Chat Transcripts
Although it all starts with the written word, as I said at the beginning of this chapter, the word ends up being ephemeral and fleetingonce you close your chat window, the words disappear. If youd rather keep your words around, save the transcripts of your chat sessions.
To save chat transcripts automatically:
Open iChats preferences, and click the Messages icon
Select the checkbox marked Automatically save chat transcripts (Figure 2).
Figure 2 iChat can keep a record of every text chat for later reference when you enable this preference.
iChat saves the sessions as text files that contain special formatting so that when you open them later in iChat, you get the full visual formatting.
The files titles are the names of the people you chatted with, and can be found in the iChats folder within your Documents folder. Click the Open Folder button in iChats preferences to automatically open that folder.
To save a chat transcript manually:
Choose Save a Copy As from the File menu, or press
Choose a location on your hard disk, give the file a unique title, and click Save.
To open a chat transcript:
Double-click the file in the Finder to open it in iChat. You can also choose Open or Open Recent from the File menu, and then locate the file.
* Tip Frankly, its insane to try to find a chat transcript by rooting around in the iChats folder. To work effectively with transcripts, check out Logorrhea (www.spiny.com/logorrhea/), an application that offers a sensible way of browsing chats plus a search feature for scanning the conversations. Logorrhea (which means pathologically excessive talking) is freeware.
Helpful Tips for Better Chats
Is the quality of your audio degrading as you talk? Mute the connection, then un-mute it. iChat re-evaluates the bandwidth thats available and improves the connection.
For a strictly bare-bones message window, choose Show as Text and Show Names from the View menu; set all incoming messages as one uniform font and size; and set the senders balloon color as Clear.
Audio chats operate one-on-one; you cant have multiple audio chats going on at the same time. If someone in your Buddy List is currently involved in an audio or video chat, their audio or video status icon appears dim.
Audio chats are full-duplex, which means you and your buddy can speak at the same time without getting cut off (by the technology anyway; whether one of you tends to cut off the other in conversation is beyond the help I can offer).
You can minimize the audio chat window to the Dock and continue your conversation without interruption.
To find out how long youve been chatting, open the Connection Doctor, which displays the call duration.
Who stopped the music? If iTunes is running in the background, your music is automatically paused when an audio or video chat begins. When the chat ends, the music starts again where it left off.
Does the audio coming out of the built-in speakers of your PowerBook G4 or iBook sound tinny or flat? This is by design: to reduce audio feedback from the internal microphone, the sound from audio and video chats comes out of the left speaker only, and in mono. Connect a set of headphones or speakers to improve the quality (though its still mono). See Apples support Web site for more information (docs.info.apple.com/ article.html?artnum=93214).
If you're using a DV camcorder as the video source, and it's shutting itself off after a few minutes, remove the tape.
Using a USB Webcam?
Although not officially supported, you can use some USB webcams, thanks to Ecamm Networks $10 iChatUSBCam (www.ecamm.com/mac/ichatusbcam/). In fact, according to the developers, it enables you to use iChat videoconferencing on machines that fall below Apples recommended guidelines.
