im involved w/ online gaming and i belong to a clan.

recently we came under attack from 1 hacker (don't know who it is) who is unhappy with us. basically he is just defacing the site. but, in addition to this he took control of the admin possition on our board and banned all the other admins. so basically he runs the show. banning people etc...

because of the hacker, the guy who runs the forums had to shut them down until we can stop him.

basically im crying for help.

what can we legally do to try to stop this?

any help would be greatly appreciated.

if talking through an instant messenger service would help let me know...
