In the admin section you can select wither or not each user can display an avatar or send private messages. How about one in there that will disable the person ability to post on the forums? This kinda don't work for me even if it is added i use F-pro but i think it would be a great feature for others. You know you got the couple members who just cant help but to post stupid stuff but instead of suspending there account just take away there posting ability for a week or 2 give them time to think about there mistakes.
