Age limit for certain forums

[dirtymerc]

I want to know if somone could hack up a little code for a way that only people 18 and older in their profile can enter a certain forum that is for only 18 and older people. The hack would install and I could edit forums to enable this feature if needed. Thanks so much guys.

to me it doesn't seem failsafe as when people sign up you only have their word on their respective ages, so there is no real way to judge this as far as I know it goes off the date of birth you enter when you sign up,if I am wrong please let me know.

Thats fine, by them filling in their age, they are giving written consent that they are of age, and thats all that matters.
