Well... you're already "approved" so to speak.

Having everyone's first 5 posts reviewed & approved, prior to being posted for the general community to read, is simply a way of attempting to make sure that new members have some basic understanding of what the expectations are here on PC. The administration works diligently to ensure that PC is a safe community.
Things move pretty quickly here on PC. It can take a bit of time to become known. However the more you post, & reply to other members' posts, the more a part of the community you will become.

By the way, there is a regularly scheduled Bipolar support chat you might want to check out. Here's a link to the community calendar:
