Sounds cool Elderon. I always wanted to be part of a forum club, or whatever.
Some general ideas...
Would be a journal I guess.
Have the members actually meet on Titan so we get to know each other in-game too.
Assign ranks (kind of like linksack and linkpearls, you get the idea)
Some thread ideas...
N00b Lookout (in-game)
Help forum (any questions?)
"Help me!" thread (in-game help)
Am I kind of getting off topic here? If the purpose is solely for nuking bad posters, can't really help you with that. It's always fun if we can all get to know each other too.
Answer the above before I try to think of any other ideas
