Meet organizers, you can have a pilot registration system at no cost to you. You
control it and 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 the competition, and gets them to
pay in advance. You'll find a pilot registration form template and tracking
system that does this for you with a few minor modifications
here.

You can set this up on your own web or blog site or use Google's. Modify it to
your tastes.

For example,

A speed gliding registration implementation is found
here with organizer comments
here.

A different approach is to use an existing on-line service that has a pilot
registration system up and running with a centralized database that can be used
for multiple competitions. Brett Hardin,
Bright resident, has a paragliding pilot registration server available here:
http://ozparaglidingcomps.com (click the "More info" menu item to see the
list of feature) and here:
http://usparaglidingcomps.com. With a few tweaks he says that it could
handle hang gliding meets, although he's not sure he wants to support them.

An existing on-line pilot registration system like Brett's for hang gliders (and
paragliders) is found at http://goflyxc.com.
