You should allow multiple score submissions anyway ... =\
I mean, if the only reason you're not allowing that is because it'd be too hectic, you can always get someone to help. And if you don't want to do that, you can always just say something like "Have 'Round 2 Submission #1' in the title or I probably won't read it."
Its ok I think I will manage though. I'll just stick to the order of posts, I've been reading all of them. I never organized a tourney before so I didn't know how it would be like to keep track of it,but its not so bad.
