I just found this site, and one of the first things it did when I registered was to ask for my birth date. - so AG would know how old it's Users are - it just needs to examine its database for that information. Through that use, it can set up separate Adult only boards - not just to discuss "Adult" type info that the original poster suggested, but to comment on the current crop of excellent games to hit the market - all of which have a MATURE Rating......
One thing I worry about on these game sites is sickos trolling for young kids, especially in Chat rooms - I'm sure you all know what I mean.
Is there a way to stop it? I guess we really have to police ourselves - if we see something odd going on, we should copy the Chat Log and send it to someone in Charge. (been there, done that).
