Whoa, I was going to say no for that one, but I realised how many categoric challenges there were, as they were overtaking the Lemmings Discussion board. But now, I say yes. Which reminds me, I would like to delete my maximum skills thread, because I locked it thinking that everyone didn't like it very much.
Also, I don't like the weighted version of the minimum skills thread, because I once posted results until namida said no, and then this turned into an agreement which made the whole topic so unpopular. I would close down any threads which rely on agreements and arguments by all users if only I had the chance to be a moderator.
