Every member gets a permanent profile page: juuhudi.co.ke/u/yourname — all your live listings, your ratings, your verified badges, in one link.
Put it in your Instagram bio. Share it on WhatsApp Status. Anyone who taps it lands on everything you're selling, with your trust profile doing the talking. You choose your username during profile setup and can change it in Settings (once every 30 days, so choose something you'll keep).
