Well, that's that
Looks like I successfully changed the template. I miss the old one already. *sniff*
I'm also sad that I've lost all the Haloscan comments. I'm switching back to the Blogger comments because they have the feature that emails you when you get them (Haloscan actually did have it, but you have to pay for it). The Blogger comments don't seem to have all the problems now that they had back when I started using Haloscan (really, it's that Blogger itself seems to be much more stable), and they work properly with the new template (with the old template, which was designed before they had comments, they wouldn't pop up from the main page).
Technically, I still have all the Haloscan comments stored in my account there, and in theory, I could cut and paste each one into the Blogger comments just so I could keep them attached to the posts. Obviously, now, I don't have time to do that, but I'm compulsive enough that I might just do it at some point.
Anyway, that's all for now. We now return this blog to hibernation.
