Give him some time. He gets slammed from time to time. You can also call us directly and ask to talk to Brie his assistant and she can put you on the list aswell. Just let her know how to get the deposit forum to you and she will take care of you.
David answers emails in the order he receives them so I'm sure once he gets caught up on emails he will get you set up
Last time I checked the m4 was at 5-7 and the m3 was 2-4 but that was last week could be more best to get in now if you can and that goes for everyone
Shoot me a pm with your contact info and ill personally call David and follow up for you
