Yes - there's a problem and I'm trying to fix it. Some experts at Vbulleting (the company that makes the software for the forums) are trying to figure out what's wrong...
Sorry about that - I am closing this thread now though as it's being discussed at the feedback forum and I want to keep all updated on the subject in one place.
Sorry about the inconvenience Sherral and others (I know some are getting the notifications, only some aren't).
