Suggestion - you could go through all the accessmasks in phpmyadmin if you're that concerned about it. I was always bugged that vBulletin didn't have a better method of listing who had access to what forums... that gives me a hack idea, actually, so I'll get back to you whenever I've written it (i.e. "tomorrow," i.e. probably next week or something) You can then install it or not as you choose, it doesn't affect me either way. It'd probably make working with access masks a heck of a lot less scary though.
