Just to add, when I got accepted (Nov. 8--Mid Thursday, so they update AIS on that day too), I didn't even have the four tabs, so don't fret everyone else who doesn't see it...
I got the tabs probably the beginning of this week. Yesterday I got my letter in the mail!
I went this past weekend to A&M and I asked if Mosher would be full right now and they said no/most probably not (I don't remember which lol). So don't loose hope!! Hopefully it isn't because im going to apply tomorrow for housing.
They said the new dorms are almost more than half filled!
