The TOTSE backyard ballistics forum - a forum for those new to pyrotechnics.
The Explosives and Weapons Forum - a forum for people who are very experianced with explosives. It's like a communist state there, the mods control everything: what you say, where you say it, and whether you can even say anything. I've been registered there for a while, but I haven't posted because I don't want to get banned and not be able to read it. There's a 2 week waiting period before you can post.
