Also, I echo the UT Austin frustration. I lost a lot of sleep over not being able to change my SOP once I uploaded it. YARGH!
I think I only got to choose my username (or use my email address) on one app. The rest I have to go through my email inbox every time I want to login so I can find the random jumble of letters and numbers they assigned to me (I know, I should probably just put them in a document). And you would think considering most of the apps go through ApplyYourself or whatever it's called, you would be able to transfer basic info like your name, birthdate, address, etc. from one to the other instead of having to write it out each time. If I ruled the world....
