Want a small lightweight program to talk to all your friends in? Ever looked at Miranda? It is a small program where you can do this< I think you can in Trillion also but this little thing also works great and hardly uses any kind of resources I been using about two weeks now with no problems with it so far I can talk to my friends in Yahoo and at the same time talk to others in AIM.
Miranda includes support for AIM, Jabber, ICQ, IRC, MSN, Yahoo, Gadu-Gadu and more. Additionally, with the choice of hundreds of plugins, icons, sounds and other content, Miranda IM gives you the ability to modify, customize and extend functionality to make it your own.
