Hi Just some thoughts You have two breeds of guides 1) well funded with dozens of paid editors and relationships with education and government 2) innovative grass roots initiatives
These grass roots initiatives struggle and often fall by the wayside. However collaboration and connection with other grass roots initiatives help to keep them afloat I would be more than happy to help in keeping the london guide alive, but as the mailing list shows there does not seem to be anybody withing open guides who is free to keep it going.
