Guys just to be clear...there's two status pages:
One from the GIAC...once they receive all your documents (transcript, etc.) they process and forward to the adcom...once they process the status changes to something along the lines of forward to the adcom for review
The second status page is from the adcom, which you get on the application site. This status page never seemed to change for me....I've been admitted to UT and it still says 'Application Submitted'. I did get an email yesterday saying it will soon change to give me access to the admitted students site...something I'm still waiting on.
I hope that helps...but the moral of the story is that with UT I wouldn't depend to much on the status pages like for other schools. If you need an update, I don't think its an issue to call them a couple times and find out where they are in the process, as long as you use your discretion.
