Google Talk:Login as Multiple Users

Many users, including myself, like to have several different personalities on IM–Work, play, etc. By default google talk with only allow you to run instance of the program at a time. Here’s how to get around that…
Run google talk with the following switch: /nomutex
If you installed google talk to the default location, you can easily create a shortcut to this setting.

1. Right-click on the desktop
2. Select New3. Select Shortcut
4. Paste this into the text box: "c:\program files\google\google talk\googletalk.exe" /nomutex
5. Click Next
6. Name it whatever: Google Talk Multiple, etc.
7. Click OK until you are done.
