Me and my friend had a ton of fun playing storm the castle, which is a community level from the workshop. I bet other people would have fun competing for levels in the workshop. Not sure how you would choose which ones to add, but i know storming the castle is a ton of fun to try to get good time. I streamed 2 runs of it and got 9:06 on part 1 of the map. Heres the stream, let me know what you guys think.

Its a good idea, however its simply not something that we believe would have an active community behind it, and as you mentioned it would be difficult to properly judge which maps deserve a spot on the leaderboard. Hope you understand.

P.S. Nice run :)
