EDIT:
THE MODS HAVE SCREWED US OVER AGAIN.
Everyone who posted on the new MBs is now ranked as "Alien". That means we can't possibly know what the users' ranks were before this "alien invasion".
...as BCGirl said, maybe we should just go with "He/she had [rank before invasion] as his/her last known rank before getting Alien" or something, and display the "Alien" rank below the avatar.
What a mess.
