Google Hack - Running more than one Google Talk
Here is a cool trick which allows you to run more than one instance of Google Talk. I found it quite useful since I could keep my wife’s ID also logged on all the time.
Right click on the Google Talk shortcut and then add “-nomutex” as a parameter in the target field. The diagram on the right should clear any doubts you have! Voila! now everytime you click on Google Talk you get another session.
