Ironically, the IM central server also provides an advantage over both direct messaging and<br />

chatting. Since instant messages are directed to a single person, the server can store them until<br />

that person logs on. Thus, you can send instant messages to people who are offline.<br />

NOTE Double-clicking names on your buddy list will always start a conversation, but the<br />

mode used depends on the situation. If multiple buddies are selected, double-clicking always<br />

launches a chat. If a single buddy is selected, double-clicking will start an IM session, unless<br />

you are communicating via Bonjour, in which case double-clicking will use direct messaging.<br />

Audio and Video Chats<br />

Like you, people in your buddy or chat participant lists with video chat enabled will display a<br />

camera icon. Clicking this icon will invite them to video chat and present you with a video preview<br />

window, giving you a last chance to get the spinach out of your teeth. If they accept, you<br />

will see a picture-in-a-picture video screen.<br />

NOTE If your buddies can only support audio chats, they will have a telephone icon. Clicking<br />

this icon will invite them to audio chat instead. If a buddy can’t support either, they will not<br />

have an icon. If, however, they have an icon, but it’s grayed out, that means they are already in<br />

a video chat.<br />

As with text chat, video chat can support multi-way conferencing, as shown in Figure 12-7.<br />

Depending on the speed of your computer’s processor, you can video chat with as many as three<br />

people simultaneously. Chat participants can be selected when you start the chat, or they can be<br />

invited late by pressing the + button.<br />
