I just realized last night that Gaim has been renamed to Pidgin.
Extracts from Pidgin website (http://pidgin.im)
We’ve got a new name, a new look, and a ton of new features, but we’re still the same old instant messaging client you know and love. We’ve changed our name as part of a trademark settlement with AOL, and have finally released our long-awaited version 2.0.0.
The project’s website in sourceforge is also moved to a new url
For Ubuntu feisty users, unofficial deb packages are available at http://www.getdeb.net/
