Random notes collected from looking around the map
Private road to Arragon and public footpaths in the area would be good. Are OSM permitted to use data from IOM Gov survey, and is this at a suitable scale? Would GPS survey be better in any case? Is anyone working on public footpaths in general?
Santan church not marked, but the Old Vicarage is. Is there a job for someone to mark all active IOM churches? (To include 'Cat with no tail' pub!)
Port Grenaugh Road is mislabeled as Ballavale road. (probably drawn as one 'way', then split)
