How to Run Multiple Yahoo! Messengers and Login to Multi Y!M Accounts
For Yahoo! Messenger with Voice 8 users, it’s now possible to run multiple instances of Yahoo! Messengers (polygamy feature) and log into multiple Y!Msgr accounts with just a simple registry hack. So if you need to open and log-in multiple Yahoo! Messenger accounts as you have a few Yahoo! ID or various other reason, just use the small registry registration file below that once click, will modify and merge the registry setting required to run and execute multiple Yahoo! Messengers at the same time on a computer.
Download ym8multi.zip, extract it and run “ym8multi.reg” contained inside the archive. Once the registry is patched, you can now starting and running multi Yahoo! Messenger with different login or Yahoo! ID accounts. If you want to uninstall the patch/hack, download the ym8multi_uninst.zip uninstaller which contains ym8multi_uninst.reg. Once double click on this uninstaller registration registry value file, it will edit the registry value and set it to disable the ability for Y!M 8 to launch multiple copy of instances.

If you prefer to edit and change the registry setting yourself manually, without using the above registry registration file, simply launch the registry editor (type regedit at Run command), and navigate to the following registry branch:
HKEY_CURRENT_USER\Software\yahoo\pager\Test
Then, on the right pane, right click on the registry editor and select “New”, then create a new DWORD registry value. Name the new registry key as Plural, and assign it the value of 1 (decimal). If some case, the value of 2 should also works. To disable or disallow multiple instance of Yahoo Messengers, simply change and set the “Plural” registry key’s value to 0, or delete the “Plural” key.

[...] Other than Windows Live (MSN) Messenger and Yahoo! Messenger, users of Google Talk (GTalk) can also let Google Talk go to polygamy, that’s running multiple instances of Google Talk and login to multiple Google accounts on Google Talk. The polygamy trick can be done without any crack, patch or hack, with just a simple command line parameter or switch (/nomutex) appended to the Google Talk shortcut. Ability to polygamy running multiple Google Talk is useful if users have multiple Google Talk accounts (or Google or Gmail accounts that used to login to GTalk) or multiple profiles or personalities, and don’t want to log on and off from one account to another account every time when want to switch, or want to log in to all accounts at the same time on the same computer.
