After one copy is opened make a new shortcut for Google Talk but at the end of it add /nomutex. If you installed it to the default folder then your shortcut should read "C:\Program Files\Google\Google Talk\googletalk.exe" /nomutex. Open 2 instances of the software on every user's computer. After this start a chain: User 1 should connect on one instance to user 2. User 2 will connect on his second instance to user 3. User 3 will connect using his second instance back to user 1. With this chain everyone is connected to everyone.
Nickname & Status Message
* You can change your name in the Google Account page.
or To change the nickname need to go to your Gmail account and change the name there. Choose Settings, Accounts, and then Edit info. Click on the second radio button, and enter your custom name.
As a result all of your emails will have that nick as well, there is no way to seperate the two.
* You can add a website in your custom message, it will be clickable when someone opens a conversation window with you.
* You don’t need to say Yes or No when someone wants to add you as a friend; you can simply ignore it, the request will go away. (On the other hand, someone with whom you chat often will automatically turn to be your friend, unless you disable this).
* The Gmail account 'email@example.com' can't be invited as your friend.
Sound & Video
* It's possible to broadcast music, MP3, etc.. through Google Talk.
Unplug your microphone. Double click on the speaker icon in the lower right corner. This will open
up "Volume Control". Select "Options" and then "Properties". Then check the button
next to "Recording" then click OK. You may also have to change your setting under
Mixer Device. Now the Recording Control screen should be up. On my computer I selected "Wave Out Mix". Click on the green phone in Google Talk and call your friend.

* There was a hidden game in Google Talk. In the about screen you could see 'play 23 21 13 16 21 19 . 7 1 13 5'. Each number represented a letter. a=1, b=2, c=3 .... When you translated this message it said: 'play wumpus.game'. To play this game you had to invite email@example.com as a friend. firstname.lastname@example.org is always offline now. You can still play Hunt the Wumpus here.
