scMdraft please ;)
For melee mapping, you won't find any real improvements in the new version.
If you are doing extended terrain, the copy/paste tool has been improved and I think SI even added brushes similar to SF (didn't test it myself yet)
lol I'm pretty active
As for the scmdraft thing, I don't have it, nor do I really care much about it. Staredit does almost everything I need, and the few special things I can do with my outdated scmdraft, where you couldn't copy/paste. If someone gives a link I will upload it.
As for the admin list, 5pool is not an admin as far as I know. Nastymarine is also not an admin, he deleted his admin account or something emo like that.
