So you got your shiny new Ubuntu Unity going, maybe even on the newest 12.04 Ubuntu release. Good stuff right? But oh no what's this, sad face - you just closed the Pidgin buddy list and you can't find it / unminimize / unhide it. Tragedy. Well good news friend, the fix is easy. Click the little envelope icon in the upper right corner and there should be an entry for Pidgin Instant Messenger. All is well with the world.
