Problem w/ 'Unread Forum Posts

Every once and a while, whatever's keeping track of my unread forum posts resets so all posts become unread. It has happened at least a half-dozen times in the past few months. This is extremely annoying when I'm trying to follow specific conversations. [Using Firefox on Mac OS X]

While I'm here talking about the forums, why can't I preview my post before I post it?

Would GG consider moving to a better forum system? Why not use phpBB?

Edit: ARRRG! Twice in one morning!
