I haven't tried to write a blog post on the new site yet (though I plan to do an analysis of Demon's/Dark Souls) so I'm not sure if it applies here, but I was trying to fix the formatting on one of my old blog posts and when I saved my changes, it saved it all as a comment at the bottom of the blog instead of just fixing the original. The original appears unchanged in any way. It's a weird issue.
Also, it was mentioned in a month-old thread, but I can't even figure out how to delete unwanted old blog posts either. If anyone could help me out with that, I'd appreciate it.
