So honestly my interest is a bit selfish, I use a running app that has wrong geo data and it bother me big time, I found out that the data comes from GeoNames.
Now seeing the UI and looking to edit a few items I'm most. The site really has ZERO documentation help resolve some issues. I fully believe the issue all starts with lack/poor documentation. What should be listed at all, in my instance a mobile home park is listed as a "class" being a city/village, with a code of populated place.
What are the purpose of each code? They must have a meaning but how does one find this out? Where of where is this info stored? How does one just stumble across it? This is just leading to bad information.
