I've made a few more anti-spam modifications around here -- if anyone's curious, this site has a great roundup of anti-spam tricks for Movable Type (although I'm still waiting for an anti-spam hack that puts a mandatory check for an existing session in mt-comments.cgi. Nerds? Nerds? Where are you?).

Anyway, the reason I mention this is that it might've broken the comment or trackback systems on some pages. If you find any of those, please let me know by email or in comments here.

UPDATE: Yup, I broke something. Thanks to Kriston for pointing it out via email. For those curious, the specific hack I applied is item 2 from the linked list. The problem I ran into is that a number of our templates had mt-comments.cgi hardcoded, rather than using the correct <$MTCommentScript$> syntax (which gets automatically replaced with the name of the script as it appears in your config file). I know, it's fascinating.
