I cannot suggest improvements to Places Database
I have tried several times now to add Alternate Names or Reference Links to existing places and the popup screen requires a valid URL. However it does not recognize anything as a valid URL, neither www.familysearch.org nor www.microsoft.com nor the URL I have already submitted for Suggest A New Place. That last popup takes the URL www.digitalhorizonsonline.org/digital/collection/p16921coll2/id/4024 (Standard Atlas of Rolette County, North Dakota) with no problem but trying to add to an existing place? No go.
