The main site and the forums need to be merged.
By now you have noticed that you need two seperate accounts to post on the main site and the forums. Basically, the creation of the blogs section created a second forum. WE DO NOT NEED A SECOND FORUM. I suggest that the main site and the forums be merged somehoe (if it detects the same IP adress on both the main site and the forum, the acounts should be merged).
