Using Google Talk
Gmail includes Google Talk, a built-in chat gadget that you can use to send and receive instant messages with your colleagues. You can also chat with anyone outside of APU Wifi who uses Google chat or AOL Instant Messenger (AIM).
Voice and Video Chat:
Want to hear and see the person you're chatting with? Just install the voice and video chat plugin to start having real conversations right in your Gmail window (see instructions below).
Google Talk Clients:
Recommended: Also install Google Talk—a standalone instant messaging client—which you can use outside of Gmail. With Google Talk, you can set up email alerts that pop up in the lower-right corner of your desktop whenever you receive a new message—even if Gmail isn't open (see instructions below).
To open the Chat gadget:
Click Chat in the left pane of your Gmail window:
To find a coworker with the Chat gadget:
The Google Talk gadget shows a list of people you've recently communicated with. You can also find a coworker by starting to type his or her name or email address in the Search, add, or invite field. For example:
To start a chat:
Simply point to a user in the list or search results, and then click Chat:
Note that a green dot appears to the left of a contact who is online.
To chat outside of your Mail window:
If you're chatting with someone, you can click the Pop-out arrow to use the Chat gadget outside of your Gmail window:
To set up chat options:
In your Gmail window, click Settings in the upper right, and then click the Chat tab. You'll see options for saving your chat history, voice and video chat, sounds, emoticons, and more.
