I'm going to be testing out some new blogger templates today. This white-on-black has got to go. But I'll merely be replacing it with the standard Blogger templates, unless anyone web-savvy enough can send something along that looks nice. I have no idea how Haloscan will react to all of this and what will happen to comments, but hopefully it will be fine.
FURTHER UPDATE: Apparently, if you direct-link to the older posts, Haloscan comments won't show up on them. I have no idea why. The comments are there if you read the posts from the main page. This glitch doesn't appear to occur on new posts, though.
FINAL UPDATE: I figured it out. I had to republish the entire blog. That takes care of that!
