Woah, I think I actually know you Sonny, from surfing around TF2 that is. I made a lot of combat surf maps, only occasionally did skill surf, but I think I remember seeing your name somewhere.
Anyway, welcome to the forums, I think it's pretty cool here. If you'd like to get organised in map making you can watch
TopHATTWaffle's CS:GO tutorials for an awesome overview of the tools (mostly the same to TF2, I've even learned some things). Otherwise reading up on
Grazr's tutorials or the
nodraw.net articles are a good way to learn the theory behind level design stuff.
For the community we have
gamedays for organised map tests that run every Saturday, hosted by your's truly, and impromptu map tests that just run occasionally through the week. If you're interested in getting a map in the gamedays, you can join the
steam group to get the popup announcement when the new thread is posted (wednesday nights est). If you're interested in getting a map in the impromptu tests, you can join the
steam group chat and just bug the admins.
