PIDGIN - open source Instant Messaging

www.pidgin.im

Tired of having half a dozen IM (instant messaging) clients open on your taskbar (or system tray?).

Pidgin is a God send ... it allows you to use different protocols (Yahoo, MSN, AOL) from one application at the same time. Each session is in a tabbed window for convenient tracking. All buddies show up in ONE BUDDY LIST! It is amazing, fast and rock solid. Available for Windows and Linux.
