Pidgin 2.5 is a ultimate chat Clint support to access multiple accounts on various IM networks  with complete functions.

Pidgin 2.5 multi-protocol instant messenger client compatible with Yahoo, ICQ, MSN Messenger, Gadu-Gadu, IRC, Jabber and Zephyr networks. Pidgin supports many features of the various networks, such as file transfer (coming soon), away messages, typing notification, and MSN window closing notification.

With Pidgin 2.5 introduces many new features in terms of bug fixing in the areas of MSN, libpurple, Finch, XMPP, and Pidgin itself. However, Pidgin has certain unique functions like the very interesting Buddy pounce, which allows you a great deal of functionality like various notifications like a message or audio when someone logs off, signs in or returns from idle to starting off a program with the same condition.
Pidgin has stood as a worthy competitor to Trillion and Digsby. However Pidgin 2.5 fails to Digsby due to the fact that still many bugs needs to be fixed. But Pidgin’s simplicity, resourcefulness and familiar design makes it unmatchable in its own terms.
