My Thoughts about donation:
Trade section main kuch limit honi chahiye, e.g every 3k deal should cause a donation of rs 100 aor 10k per 250 or something like that. I dont think it should be an issue.
PG account mention ho, bas seller, deal kesath pg account main bhi kuch donate kar den. Trade thread main donation ki info ho, ta ky checking main asani ho.
(some years ago i used to buy/sell through souq.com in uae. They took a share on every deal, they had the rating system)
Maybe we should have a referendum or PG lovers' opinion on better donation setup.
