So, anytime I click a "sign in" link, I go to the Dashboard and find myself already signed in. But if I go back to my blog, I've still got the "sign in" message in the corner and I can't comment. I can post without a problem, I just can't comment. I've tried via google and via livejournal, and both just delete my comments.
update: I just signed out and in, and same deal. I can post and edit, not comment. Even viewing my own blog.
