FOA is getting a long-overdue upgrade: Zach is very kindly moving is up in the world from this very 1990s vBulletin world we are living in right now, to a newer, brighter world, called Discourse.
This will be happening on Friday night - the forum will go offline entirely for the migration. When you return on Saturday, everything will be completely different, however assuming everything goes well, you will be able to login with your usual username/password combination.
Anticipatory downtime tonight in preparation for the Discourse upgrade tomorrow - resizing some disks. Starting around 8pm, site offline for about 30mins.
