In early 2011 a demo was created by Gregory of No More Grapes to demonstrate the database of toilet locations held in the crowd-sourced OpenStreetMap project. The demo evolved into a full website, but by 2014 it had been not been given the attention it needed. Gregory and the ToiletMap.org website supported The Great British Public Toilet Map which has now been relaunched. A full blog post has been written on the decision to put the lid down on this website.
