Great question! The short answer is that all registrations wind up on the Speedy-Feet registration page (for 2016, use this link) so you can scan down the list to verify yours has been posted.
The longer answer is that it can never be as timely as an online registration. Your registration arrives a couple of days after it is mailed, then it is batched with others from that week, and then sent to Speedy Feet where it is uploaded. Your check goes into an envelope with other checks and at some point is delivered to one of our charities for deposit, so your check won’t clear until even later.
Don’t be concerned – it all works out given time – and once you see your registration on Speedy Feet’s list, you are IN!
