We have as many safe guards in place as we can to keep trolls out of our forum. Some get in anyway...
PLEASE, if you find a troll, DO NOT RESPOND TO THEIR POSTS. No matter what they say, ignore them. PM a mod or admin, actually PM all of us (in different PM's the forum gets cranky about multiple recepients) and we will take care of things immediately.
If you respond it makes it very difficult for us to remove posts because we will have to remove yours as well so that there is no trace of the trouble maker.
