Web search finds Glebe FC at https://www.pitchero.com/clubs/glebefc/contact with a postcode of BR7 6SD. OSM is resolving that postcode here, but Glebe FC probably isn't. The website puts the correct location somewhere in what OSM presently maps as a recreation ground at https://www.openstreetmap.org/way/190936019/ which web searches previously attribute to OLD ELTHAMIANS. I've added some previously unmapped buildings and pitches in this area, but to annotate them correctly, it would help to know: does Glebe now exclusively manage that entire area? If not, which buildings and pitches are exclusively used by Glebe and who manages the others?
