PS I know who attacked your server, it was not me but they did not authorize me to give there name. But they are in the top 10 which should narrow the field a bit.
I do not believe this is the right place to say such things... (we have private messages for these sorts of things....)
also, it does make sense to add that for groups, since in round one, I changed groups a few times. but I do know some people like to not say what groups they are in.
another thought though...would you have it be required that if you were to have group features, that it automatically adds the tag to your name? or would it be optional, since I am sure that there are some people that do not like to tell what group they are in.
