I've been bouncing around with multi-client messenger applications Fire, Proteus, Adium and now JBuddy all three apps are off to a good start but thats about it some are farther than others. I'd suggest losing the clickable company banner at on the buddy list if I need to goto your homepage I'll find out from the about what the URL is. Don't even think about putting ads there windows users may tolerate them but Mac users won't Ads = Trash Can. The interface is typical but the icons leave something to be desired and the metal skin if you can call it that isn't very metallic refer to Apple iLife apps or Safari. I have yet to test file sending or multi user chatting right now I'm just happy it connected to my other accounts. But it didn't preserve my blocked list on MSN.
