Hello cherishme22: I don't know if I know the answer to your question.

I see you have 3 posts to your credit so far. One thing I do know is that before one can enter the chat rooms one must have had 5 posts reviewed & approved. It may be the same with the Arcade.
As for the social groups, if that's what you're referring to as "support groups", many of them are for members only. So in order to participate in a particular social group, you have to join it. Here again, you may need to have 5 posts reviewed & approved before you can do that... I don't know.

I never go to the Arcade, I don't chat, & I don't belong to any social groups.
As far as the control goes, I'm not in a position to offer an authoritative opinion.

But I believe the answer would be that there are many vulnerable members here & PsychCentral strives to make this as safe a place as possible for us. It's a good thing.
