I thought this would helpfull here for contacting each other. Enjoy.

Can msn people talk to aim/icq/irc people to? (don't think so [:(])

Yes.

trillian sucks, id rather just have aim and msn open rather than getting something else

I like im2 opposed to trillian. My only complaint is the groupings, in im2, they are by connection. I would rather have one group for people regardless on if it is AIM, MSN, Yahoo, ICQ or IRC. I liked the metacontact as well. I am sure im2 will get there, it does seem far less buggy than trillian.
