Short description: Deluge is a BitTorrent client, created in an "open source" style, using Python and PyGTK. It holds exciting features and plugins, such as selecting which files to download, scheduler and IP banning system and lots more!
1.5.3 is almost out (24 hours to go), and they require as much translators as possible to translate the program to their native languages. If you're an open source mind, you'll know this is one of your duties to help maintain great programs. Head to Launchpad and start translating!
