i got an email from them about a month ago saying they've recieved my application, that it is ready for review, and that they won't be handing out interviews until september.
I talked to them since my check that I had sent way back had not been cashed. they said that none of the checks have been cashed and that they have not started processing applications yet. (This was last week).
Got a mass e-mail today saying my app has been received (I submitted 5/31) and to be patient with the admissions process, that type of thing. Looks like they haven't cashed any checks yet so don't worry.
