Apparently data I sent in for a local city was incorrect or imported incorrectly (along with a LOT of other areas not entered, but that's another matter as they were ALL public areas and now I know to keep a spare copy of my custom one in case i have to re-install Stellarmate again).

I have updated the actual citydb.sqlite using an SQLite editor, so it's no big deal as I can simply copy it over each time, but I may lose some other updates that way.
So, where exactly do we submit either the updated mycitydb.sqlite or the full citydb.sqlite for modification/inclusion. Do we need to join GIT and jump through those hoops, or is there a simple email address that stuff like this can be sent to?
