A noticeboard for your society, with someone checking every pin. No shops from across town, no anonymous sellers — just neighbours.
Everything is sorted by how close it is to your building. Same tower first, then the podium, then the neighbourhood.
Put two or three neighbours side by side — price, hours, experience — and reach the one you like directly.
Bake, tutor, coach, repair — list it in two minutes. A moderator checks it before it goes live, so the board stays trustworthy.
Birthday cakes, maths on weekday evenings, table tennis on Saturday mornings, a spare hand with the plumbing. If people in your society would pay for it, list it — it takes two minutes and a moderator checks it before it goes live.
