Re: disappearing comments: I have no idea why they do. While I do admit to having a tiny set of blacklisted words that will immediately get you *in* the spam folder, and never *out*(mostly the sort of not!PC language I will not tolerate here, hurr hurr hurr. censorship!111!!!!!1), none of the lost comments actually contained any of them.
So! If your comment disappears, feel free to comment a gazillion times until I notice!
