I've fixed the issue with the member map so it displays correctly again. There seems to be two markers for each user (at least with the imported ones). The imported ones cannot be edited and I think I'll have to manually go in and change or delete them. I'll look at that a bit later to give user permission to those imported.
New pilots can add their locations by finding their spot on the map and "right clicking" to add a placemark. Then just fill in your information there. That's all I've figured out so far. If you mess it up, you can also delete any placemarks you create. Please just create one place mark per pilot indicating your location as generally or specifically as you care to.
