2. Competing Music Videos

You may choose to submit AMVs to the AnimeNEXT General AMV Screening if you do not wish to compete.

The Winner (1st Place), in each of the 8 genres, will be awarded with a certificate during Closing Ceremonies of BAMCon on Sunday, June 12, 2011.
I'm not saying it's bad to model your rules after another contest's; but if you're going to cut & paste an entire set of rules, you might want to at least double check for dates and the names of the other con in the paste.
