3 Ways for Multiple Instances of Yahoo Messenger

I know most of us have more than one Yahoo email id's. To be signed in with each one on Yahoo Messenger could be a good idea.
Here are some ( two) ways to do it.

1) Editing the registry method

(i) Go to the Start menu and click the Run button.
(ii) Type " regedit " without quotes and hit the enter button as hard as possible.
(iii) The window that opens will have a list of folders in the left pane.
(iv) Goto HKEY_CURRENT_USERSoftwareYahooPagerTest.
(v) Now in the right pane do a right click and create a new DWORD and name it "Plural"
(vi) Right click over " Plural " and select Modify. And change the value to 1

That's it.

2) Creating a .reg file

(i) Go anywhere and open the notepad or any other text editor.
(ii) Copy the following codeinto the new text document:
REGEDIT4 [HKEY_CURRENT_USERSoftwareyahoopagerTest] "Plural"=dword:00000001
(iii) Save the above file with the name multi.reg
(iv) Either double click on this file or right click on it and select merge option. (The result being the same in both the cases. )
