If you have joined these forums in order to play test a specific game, and have been given a recognition code, then you will be unable to see the play test forum until an administrator has added you to the appropriate group.
At this point, entering the recognition code does not automatically add you to the group, although we are working on a modification to do this.
If you wish to speed up the process of being added to the correct group for your play test, please send me a Private Message or us the Contact Us screen.
