I don't think it's a matter of them accepting it or not. It's whether the offer will be around in October. I requested a match and they said to send in the stuff when I'm ready to start and it will start within 10 days of me sending it in. I'm quite confident I wouldn't be able to send my credentials from UA and say "sign me up on October 1", or July 1 for that matter. I am under the impression you send it in when you're ready to start the 3 month challenge and then it happens. You could probably wait until October to start but there's no guarantee it will happen. I was told in January on this same board that it was a risk to wait until June but sure enough I seem to be ok. I suppose October would be another extended risk to take.
