I upgraded the messaging system today. The problem was that every single time you loaded a new page, the script would search a 300,000 line database to see if you had any messages. So I did some archiving and now it should be more like 7,000 lines.
There were quite a few changes made though, so it's possible that something might mess up. I haven't changed the messaging since the day the site started so it was pretty solid. Let me know if you have any problems.
Also, you'll probably see a whole bunch of RAH_699RAH_699 or some random stuff like that.. just ignore it. Over time they'll go away and you'll never see them again.
