Hey jukra, BioPower sounds pretty interesting Well, I don't see any reason why it can't take part assuming that it's not Babyphone with a name change or something like that You are expected to have done a certain amount of work on your application. But one of the advantages of open source software is that you can build upon libraries and code already out there to develop new and wonderful things. If you're happy enough to outline and be judged on the work you've completed I don't see why it can't be added as a new application.
