Just playing devil's advocate here ..... but what are the legal implications here? I'd think no one would get nasty, but "what if"... a problem arose, someone got miffed.... anything like that, ..... and you get asked why a herp forum needs a password protected adult forum? Not saying (nor wishing) there will be trouble, but I would think that such a place would be very off topic for this place?
No trouble intended, just my view. Maybe I'm the weird one, but I would be more inclined to come here for herp related topics, a few laughs in the general discussion forum are good enough.
