I finally got Haloscan commenting to work. (tip: you have to upgrade your template. I guessed this, but I thought I'd have to restore all the links--turns out it transfers over. I do have to restore the formatting, though. Bah). However, it's 86ed all the old comments, I'm very sorry. I've got an archive of everything but I have to figure a way around the generic template so that haloscan works only from this day forward, so I can restore the old commentary. Hmph.
(Probably easier just to get around to switching to Wordpress and import the sucker.)
There you go. I need to go to bed.
