I'd say that above all else this contest was very succesful. 4 completed entries in about 2 months sure complies with the goal to 'bring potential to this forgotten gamemode'.

If hosting the levels publicly for playtesting becomes a problem, I'm OK with using the CDF server for it. I'd give you a temporary allaccess password and you're free to alter whatever settings are required. I promised in the poll thread to add all finished entries to that server's treasure playlist anyway.
