I've been looking at your permissions.
First of all, I released all those posts you wrote.
Second, for some reason, I can see where you've got the "Moderate Posts for this Group" in your profile, so it's not a total system glitch; I just can't figure out which group you're a member of that is causing this to be turned on for you.
I compared you with a few different people, but everyone's sufficiently different in preference that I can't find a common link. As it stands, you're set with the "2005 Ennies staff, 2006 Ennies judge, "gamestore publishers", "staff:Newshound" "staff:reviews moderator" and "moderators" selections. (Not "Super Mod," just Moderator, which is a hosted forum leader-type setting.) If any of those would definitely NOT apply to you, I'll try turning them off and see what happens.
Only answer I have right now is to pull an "eyeglasses test" with you (I turn a group off, you tell me if you can post yet.)
Unless someone changed some group settings for one of those groups recently, I'm not sure why it suddenly kicked in.
