The glideports were/are populated by Glideport.aero. I imagine Pedja used some préexisting database as he populated the entire globe to the best of his ability.

To double check that your glideport is not listed please select "show all" in the left hand tab. If you still do not see your glideport please send Pedja an email with your glideports name and latitude longitude. You can find Pedja's email on the glideport.aero site.

Thanks for pointing out a missing site.
