Right now, as best as I can tell, the email system is broken. New PMs are supposed to trigger email notifications to users. So you may have PMs and not know it until you check the forum. Consider emailing somebody if you don't hear back from PM within a few days.
Furthermore, the site will have downtime this weekend, possibly into next week. It will be sporadic. The site should not be fully offline, just somewhat broken, during those times when it's being recoded. If something doesn't work, feel free to email (or try to PM me) about it. Or email Savage, and she'll pass it to me.
An email will be sent to all users when maintenance and upgrades are complete.
