Alternate MSN messengers?

[Navy Blue]

Can someone please name all the alternate MSN messengers? I used one for the longest time, and I just bought a new computer and did not transfer over the messenger, then wiped my old computer.

I know Windows live messenger, Meebo, and eBuddy. Please name all others.

Pidgin? Trillian?

No. Never heard of them.
