You might notice that EVERYTHING in the Forum is either New or Updated. Actually, the search database became corrupted and I spent the better part of the day tracking down the problem and correcting it. In the process I had to completely rebuild the search table in the database. This resulted in everything being marked as unread. Additionally, the first post in each thread says that I edited it, even though I didn't. Hopefully this won't happen again.
Sorry about that.
If you wish to clear all of the New and Updated messages at once you can do so by selecting "Mark all forums read" from the Forum Tools located at the bottom right of the Forum listings page.
