Pidgin

I have my friends scattered across on different IMs -Yahoo,MSN,ICQ,Google and AIM.

Previously I used to use Trillian from Cerillian studios to use one client to integrate the friends' lists on these services.

Lately,I came across a very neat application that does this integration much better.The software is called Pigin.

The best thing I liked about Pidgin is its clean interface and the Tabbed windows.

One can install additional plugins for extra features.

Pidgin could be downloaded from http://www.pidgin.im/
