Hello,
As I never heard clarification from you on my question, I am closing this topic.
The way I read this question is for other servers to display all of the free sceneries available for Flight Simulator. The Wishlist category is only for requests that can be fulfilled by Microsoft and/or Asobo.
The closest thing that the team can do to deliver this is to provide a freeware category in the in-sim Marketplace for people to contribute to. There is a Wishlist topic for that, and if you are interested, you are welcome to vote for it, if you ever return to the forums:
Freeware category for MSFS Marketplace
In the meantime, the link provided by V1ROTA7E is a very useful tool to download a lot of existing freeware available today.
