Anyone who has been approved for this program and paid or will pay the $99 fee, when did you apply?
I applied the evening of the 6th of March was "rejected" on the 14th of March and was finally approved on the 28th of March.
What does it mean when you never got either emails after signing up about the same time as you?
Apple is still processing lots and lots of applications and just because you haven't gotten in yet doesn't mean your application is lost or rejected or anything...it just means you haven't gotten in yet. Reapplying under another Apple ID means they have MORE applications to process before they get to everyone.
No one knows who they're excepting or why they choose certain people. Just wait, there's not much else you can do (legally).
