Not to sound rude or offenseive, but maybe when you get your Hacks number up to oh, say about 12 or so, AND get a message board with almost 150,000 posts, maybe then you won't need to ask a question like that.
My hack does work as-is for me. That makes sense because I developed it for my board. Admins can close any thread with it; Moderators can close threads in their forums; and members cannot close any threads, even their own. This is the default way vBulletin works in terms of who can close what thread, and it's the system I use. My hack works fine for it. Aparently, although I haven't tested it yet, I guess pwr_sneak's version works for ALL situations.
As soon as I am able, I will test his update and fix my hack with it (assuming you, pwr_sneak, don't mind if I do that?).
