The online map / dibber reservation service is designed to guarantee you a map, and if you require it a dibber, and to minimise on-the-day form filling. Participants with a reserved map just pay and run.
Logon is required before you can reserve a map to minimise spam map reservations and also to give participants the ability to review, delete, or modify by deleting and reentering, their reservations.
There are several options for login: Facebook, Google, Yahoo, OpenID choose whichever is most convenient for you. Some of these will ask you to trust maptypes.org with your data and you will need to say yes. Only a userID is actually requested.
