Make him an Admin that should do it
phpBB is rather simplistic and basically idiot proof compared to others i've used, but I've been running forums for 15+ years so it may be just that i'm used to all the forum software out. i'm sure you'll get it eventually. To start confirm his permissions, check restrictions for new account, post count, birth of account. Check his group cat permissions as well, try resetting his account rank status. Those should help get you started, then go on from there. Also did Nick change any security settings when those one pricks were on the board, as well as the spammers recently? that may be worth looking into depending if he changed newly created accounts, since Husky is about 1 week old and we've had spammers for the past couple of weeks.
(don't really make him an admin...that was a joke)
