Gaim is now known as Pidgin

One of the leading open source instant messaging systems is Gaim. Gaim stood for GTK+ AOL Instant Messenger. But due to constant legal pressure from AOL, time and again, the Gaim developers have finally had a settlement with AOL and while they cannot say why they have changed their name, the name has been shifted to Pidgin.
Good luck in continuing the wonderful open source instant messenger client, Pidgin development crew!
