Clear LiteRumble history

I have created my own LiteRumble instance running as a google app, as described in previous discussions. Now I want to know if it is possible to delete the battle history and the participated robots? I am experimenting with it since we want to have a roborumble event at our office and I want to delete my previous "testing" robots and matches and have a clean slate when we do the event.

You should be able to delete the data from the AppEngine web console. Otherwise you can simple make the clients upload to a different named rumble, and the old one can be for the demo/setup bots.
