Log-in Multiple Accounts in Yahoo Messenger 9.0

If for some reason you want to log-in multiple accounts to your favorite messenger YM, you can do it in a simple registry hack.

1. Click Start Menu à Run
2. Type regedit and press enter
3. Navigate to the following registry branch (HKEY_CURRENT_USER\Software\yahoo\pager\Test)
4. Then on the right pane, right click on the registry editor and select “New” à DWORD
5. Name the new registry key as Plural
6. Assign it the value of 1 (decimal)

To disable or disallow multiple instances of Yahoo Messengers, simply change and set the “Plural” registry key’s value to 0, or delete the “Plural” key.

In my work we used YM as a messaging tool, and I don’t want to used my personal YM for my company use that is why I need this.
