Additionally, you may want to take a read through the Sandbox FAQ (linked at the top of the forums, on the upper right) as it does have some relevant information to your question.

Reason: Moved to Sandbox support as this is a support request.

I'll say it right now -- my head hurts from trying to get the birth date verification to work. Big pain in the rear right there.

I would believe I have won.

Just adding the hidden forum real quick and setting permissions. I'm just about done.

Pfft. At least I've got the legalese done. That, in itself, is the most difficult part.

Race? Uh oh. o_0

Age verification would be to catch the stupid people that can click a button that says they are old enough, but can't enter in a birthdate that would prove they are old enough to view the page. And there would be a disclaimer anyways...though, I don't have the exact nature of the disclaimer written ...

I'm actually thinking of implementing this into the forums here, however there would be some coding I'd have to do for age verification. I'd expect it to take some time to get it up and running, but it'd mainly be because I am picky about how things are coded on the forums.

I'll make this clear right now, even with an "adult" forum, there would not be any indecent content tolerated whatsoever (i.e. pornography, extreme profanity, etc.)
