They're still hammering out details of the contest, but as it's a chorus battle, it will be group songs. They're still deciding whether or not we will have to find out own groups or whether they will randomize groups. However, not to worry-even if you're new, I'm sure people who don't have a group will band together, and if you don't know how to go about that I'm sure the organizing staff might be able to help.

I would imagine how you want to do the video (pictures or animation or whatever) would likely be up to the groups, however I'm not really sure as I'm not one of the people organizing the event.
