Why can't I edit my blogs?

We've had some issues as of late with a couple of members deciding that they no longer want *anything* they've ever written here to be visible, and thus went on a post-editing rampage. This wreaks havoc with forum threads, so, at least for now, post editing has been disabled. Blogs use the same input module in Drupal as the forums, so, sadly, they're affected as well. Hopefully in the not-too-distant future we can put things back the way they were.
