there is a way you can have usergroups, on another forum i go to there is an adult off topic section, where topics inappropiate to be viewed by young age can be discussed.. on there, its limited to people 18 and over.. this can be implimented relativley easily, just like the moderator and admin usergroups only can view the staff lounge and spam archive, so you could have a section just for members over 18.. im not sure about this for here, but it can be implimented..
