After getting all excited yesterday when my 5th & final referral went through (free iPod coming!), I woke up to find that my account had been placed on "Hold" due to some discrepancy on a couple of the referrals. They were two people that I had signed up on my computer (talking with them over the phone to get their details) rather than them doing it themselves. Guess they thought that it was just me signing up three times or something. Anyway, emailed them this morning explaning & waiting to hear back from them again.
