Just so there's a thread to make the details easy to find and so that everyone is aware of it, I've set up a small 4 person server at eu.tf2maps.net:27030 so people can load up their maps and run through them and leave feedback for themselves (or for other people's maps). Anyone can change the map using !map <mapname>, and anyone can use "!noclip @me" on the server. Only VIPs can upload maps, so you'll need a willing VIP to do that for you still. If this server proves popular, or frequently fills up and there's a queue of people trying to get in it, I'll make some more of these servers. Enjoy!
