tweaks to run multiple instances of google talk and Y! messenger

we think of this thing when our friends ask ues to open their account either google or yahoo just to check the mails and some sort of things..cant we open two accounts simultaneously???..YES we can by doing this tweak..first of all lets do with google a very small tweak to do

GOOGLE TALK
1.A Shortcut to google talk will have a target address like this on your desktop:

C:\Program Files\Google\Google Talk\googletalk.exe”

2.then do this... make shortcut with right click and make the target as

C:\Program Files\Google\Google Talk\googletalk.exe” /nomutex

and now run the short cut for second login ...

YAHOO
1.Download the registry file
2.Run this registry file by double clicking and Click yes to proceed. This will give the message ‘Information added to registry’.
3.From next time when you open Yahoo messenger you will be able to use multiple instances of it
