Robert, Am I missing something here? Go to: http://ris.dev.openstreetmap.org/oslmusicalchairs/map?zoom=16&lat=51.46829&lon=-2.60556&layers=B0TF
A lot of these have the same name in OSL and OSM, yet are flagged with a green circle. What does this mean? (Actually, I've just gone back to it and the small circles are turning into rectangles) Is there a page with a legend that I can refer to? Also, how often is this data updated these days?
