I have upgraded the message board to the latest version of vBulletin. Here are some of the new features:
- Private message sorting and filtering (at the bottom of the PM page)
- Quick reply for private messages, like the quick reply inside of threads.
- Ability to report a private message (like reporting a post). There is an icon at the upper right of PMs and you can click that to report the PM to the moderators.
- There are also some social group stuff, like adding friends, comments left on the profile, etc. We will try having these things turned on for a while, and see if they are a positive or negative for the message board.
