Hey Todd, welcome to TF2Maps, we hope you enjoy your stay. The cafe is down the hall, second door on your right. We serve free breakfast in the mornings, from 6 am to 11 am. Biscuits are on Tuesdays!
Make sure to join the TF2Mappers Steam Group (
http://steamcommunity.com/groups/TF2Mappers ), and hang around in the group chat with all of the other cool kids. You can also get notified about all the activities sent out by the group, usually announcing imps (impromptu map test sessions, you can submit your maps to the bot in the group chat), gamedays (scheduled map test sessions, you can submit your maps to a gameday thread when you see one), and other fun events. Our servers have a cool feedback plugin, where during these test sessions, people can leave feedback by using commands in the game chat, and demos are automatically recorded, meaning you can watch and rewatch the gameplay of your map to see how it played. All of that can be found here:
http://feedback.tf2maps.net/ (you can also find it at the top of the site, labeled "Feedback").
I really hope this helps you get thing started around here. We are excited to see what you make! Have fun!
