I am a veteran Source engine mapper and have been using Hammer since I'd say about early 2007, and before that I used the older Goldsrc Hammer for a few years. I have just recently started mapping for TF2. I have a project I started about 5 weeks ago, consisting of me putting ludicrous amounts of hours into it (so I can release on Halloween or the day before). It is themed, and a CTF map, but I will save that for when I release it. I just thought I'd say hello since I plan on releasing maps here and being a semi-active part of the community (really busy with university). Also, just in case anyone's curious or has played these, I mapped for Zombie Master mod for quite a while and then released a few TTT (Gmod gamemode) more recently, such as ttt_lost_temple, ttt_urban_ruins, and ttt_catacombs.
