well what content are lurkers viewing that they love so much. Funneling them into registration works for most sites that want more registered users Vs. guests.

Make the site viewable by registration only, set a cap of maximum registered users and when that reaches that number. Resort to invites and referrals to gain more users. Keeps out riffraff in the long run and makes your site more of a prize to be a member of.

just a thought..

Like someone else said, video games can and do have an impact on young minds much like other forms of media. They may pick up a fighting game and think it would be a good idea to emulate those moves with a friend or sibling. The greatest deterrent in preventing kids from reinacting the violence they see in the games they play is not ratings, but better parent involvement. It is the responsibility of a parent who allows young kids to play video games to sit and watch them play the first few times, and explain to them that the violence in the game is pretend, and to do such acts in real life could seriously hurt or kill other people. Quite frankly, I was playing GTA from such a young age it was before I knew what drugs were! However, Because I grew up playing games that enabled me to traffic drugs, beat people with a baseball bat, and kill hookers doesn't mean I commit the act in real life.

And as with anything, it has to be in moderation.
