Another misconception, both ways. First of all, as I was just reminded by someone who frequented the site as an underage 'yout,' we have *many* underage visitors to the site, some as young as 14-15 by their own admission, and that is part of the reason *why* we (the Guild) are tasked with trying to keep it PG-13 to Soft-R in rating.
Secondly (a big 'secret' known to insiders here), although we prohibit uploads of anyone under 17+ in age, *technically* that's only for site rules and good taste rather than legal reasons, as there is no *legal* requirement, *since* this is by definition not a 'Fetish' or 'Adult' site! So there. It's a nice, family-friendly, Safe For Work site, so I suggest printing up a little business-card-sized promo piece with the URL and thumbs from one of the SFW PS galleries, and putting it in all your Christmas cards this season for *everyone* to enjoy!
