Just an update - there's more broken than just the notification badge not populating. Emails aren't being sent, for any reason, as best I can tell. Not just notification of PMs, or replies to your posts, but everything - activation emails for new members, emails if you try to change your email address or password (for now, DON'T try this; you'll likely get shut out.)
Reminder: If you do hit this kind of wall, and cannot log in, you can email us at philliesphans (at) gmail.com, and I can probably get you sorted.
