What is the deal with Maplantis maps? Do we have to upload them manually, or is there someway you Admins can do it?

If Yoshi decides to make something to transfer them over, then they get transferred. Other than that, if you really and truly want anything the maps in life there, you're better off doing it yourself.

Is there any issue with just getting them for the Maplantis backup? While I hate Maplantis (because of the support of OSMap, which still needs to be removed from the backup), I don't mind going there to get most of my downloads. If it bothers you, do it yourself, as Moose said.
