I'm an admin and I have the same problem. As an Admin, I CAN wipe out an entire board but the topics within it can only be deep sixed by date expirations. that's wrong because I have old topics I want to keep and some newer ones I want to eliminate. But I can't. When I try to delete the posts within a topic instead, I get "an error occurred only the admin can delete this post!". But I'm logged in as the Admin!
