Well.. confirming what Warheck said in another thread. Even if you are in the Developers group, you can see the forum, but when you click on a topic it says you don't have permissions. I'll try to address some of the more pressing bugs this weekend, including that one.

Also, this is more of a UI flaw than a bug, but I guess it's tough to even know that an IVAN Developers forum exists in the first place, unless you click the "Forum" tab.
