wishtobeapilot,
I sent mine about a week before the deadline by e-mail (only because I'm in the UK and saw the ad late, therefoer couldn't send it by post because it would have never made it!) I have also had no response from them. I put up a thread about this you should find it if you looked into the last 10 days of this forum.
Cheers
Good luck, hopefully we'll be on the same course!
BTW
