If you registered for the site and logged into the forums, you will find that you are a COPPA user thus having to get a "parent's" permission to do anything other than post. This is because I'm using a revolutionary Joomla component called jFusion to auto create the user in vBulletin after it is created in Joomla. They currently have a bug that does not set the COPPA status of the vBulletin user when it is created. They are working on fixing this and will hopefully have a new release soon. But until then, I'm manually changing the COPPA status of the users.
Please be patient since I can't be up all hours of the night waiting for users so I can change their COPPA status. But I will get to it within 24 hours of you registering. :-)
