If you don't know what Trillian is, it's basically an instant messaging program that connects to multiple networks replacing programs such as AIM, ICQ, YIM and MSN messengers. It even does IRC, Jabber, and a few other things if you set it up that way. No ads, spyware or anything like that, too. Only thing is, it can be difficult to set up if you're not used to using the various messengers. If you decided to check it out, feel free to ask me for help.
