At this stage, summary:
Invitations sent:
$150A - 20/20 + 5
$100A - 20/20 - just sent
$100B - 18/20 - just sent (2 spots left)
Invitations will be sent out shortly:
$50A - 20/20
$50A - 20/20 + 1
$20B - 20/20 + 1
If you have registered for the $150A and have not received the invitation, then you are on the waiting list if payment is not made within 4 days.
Another option for people on $150A waiting list (no pressure of course) is to jump on $100B.
Closer to the season, usually there is added interest for a $50C league.
I'm not sure if $150B will get up but it's a wait and see.
