I've been searching for a portable version of MSN, or a version I can run next to my normal MSN just so I can login on 2 different MSN's at a time.

Do some of you people do this? What software do you use for this? I remember there was a site where you could login on Yahoo Messenger, Windows Live Messenger, AIM etc all in once, but can't find that one (or not a decent one).

Could someone help? Thanks!
