I’ve been using Trillian on my PCs for about three years now. I started cleaning up my contact lists across the different IM protocols and realized one of my biggest pet peeves: contact grouping. Contact grouping is local to the computer; they are not synced with the protocol servers.

I use Adium on my PowerBook and it does not have this same problem. Any changes I make in Adium are reflected on the protocol servers.

Is there a multi-IM client available similar to Trillian that sync with the protocol servers? I like tabbed chat windows and message archiving capabilities.

Anyone?
