We provide you with an on-line pilot registration system that you
can put on your web site.

One barrier to running a competition is having an on-line system
that automates the task of pre-registering pilots coming to your competition,
and gets them to pay in advance. We provide you with a template and tracking
system that does this for you with a few minor modifications.

You can easily set this up on your own web site. Modify it to your tastes.
