To better organize and prevent spam, some changes have been made to the permissions of the Developer section of the forum.
In short, the Developer section is now read-only to anyone who is not in one of the developer usergroups and is not accessible to guests.. These usergroups indicate which development teams you are a part of (programming, writing, art, etc). In order to join a team, go to the User Control Panel -> User Groups and then check which group you wish to join. You may do this for each group applicable to you. This application will then be approved by the Development Group Leader, or a forum admin. This gives you permissions to post in all of the Development Forums.
The General forums (including the Discussion and Ideas, Concepts, and Suggestions forums) are still open to the public.
Rationale: we want to remain open, so people will be accepted into the groups very freely. However, should they prove to be spammers or hostile to the rest of the community, they can be removed from the user groups to keep the Developer forums clean.
