Single Status Update
I was just gonna half, half, half etc each round as songs are eliminated, but as you say, a 3-way or two might need to occur. Unfortunate, but I'm dealing.
I haven't worked out how many rounds, last time it was 5 and then the final, IIRC? It's work-out-able, but I can't bear to. Again, it's just how many times the lot can be halved, effectively.
I think 66% isn't unacceptable to be honest. If you think that's too much, just say.
Polls could be stunning, but I prefer posts, as it offers discussion/interesting facts blah blah.
