Normally a couple new threads aren't worthy of a Steam Group announcement. But we need to start bringing people back, and let them know there is more activity. First the big one.

Chet Faliszek has said there will be a Q&A session for L4D mapping. A community questions list will be really helpful, so get in here; http://forums.l4dmaps.net/thread-1131-page-1.html

Second, our Tutorial section has gotten some truly amazing updates over the last week, including the decompiled L4D2 maps (shameless bump :p). If ever there was a time to learn about custom zombies, this is it; http://forums.l4dmaps.net/forum-16.html
