What IM software are you guys using?

[MikeHunt79]

I've just formatted my comp, and I used to use Trillian ages ago....

Are there any other out there worth considering?

I have an account with msn, yahoo, and icq, so I'd rather use a single client.

Was downloading trillian, but gave pidgin a whirl. It's working great. Thanks!
