Welcome to the forum. As others have said it's a lot of fun. Don't take things too personal. A couple hints, when responding, use "quote reply", that way, everyone knows who your answering. Also, try to avoid calling others "idiots", "retards", and things like that. Some 4 layer words are on the no no list although if you sort of mis- spell them, they seem to get through (ie shxt or fu, etc). You can say "your comment is idiotic etc. Have fun.
Or you can refer to them in the third person and insult away. People here care about issues. That means tempers can flare. It's better than apathy.
