This application will allow you to run multiple instances of Yahoo Messenger on your pc! Perfect for those who have several different yahoo id's and would like to be logged in to them at once. Please note that the Y!Multi Messenger versions coincide with the Yahoo Messenger versions and are build specific. Meaning you must be using the same version of each to work properly.
This is intended for the newest build of messenger and may not work properly on lower builds.
Just run the install and then start using the Y!Multi Messenger icon that will appear on your desktop instead of the regular Yahoo! Messenger icon.
How to use it:
Just double click the desktop icon to load up X amount of Yahoo! Messengers, thats it!
Note - you may have to uncheck the "Automatically Sign In" option on the login screens though or you will start getting the "You have been logged out as you were logged in on a different machine" message.
You can run the registry editing script to do this for you if you are not sure what to uncheck, go ahead...open it in an editor first if you want, its 100% safe and will not mess anything up.
