This isn't about WP blogs I have installed, but rather other peoples'.
Whenever I try to leave a comment on a WP blog, it just doesn't show up. It's not being held in moderation, I know that's not the issue. I can't figure it out.
If the blog owner has comments set up with the WP login, I'm fine. But if it's the type where you put in name, email, and website, it just doesn't work.
