I don't think people should have to pay to either see or reply to for sale adverts.
Club polo never did it to make money, they did it to try and stop scammers from ripping innocent people off which is becoming a common occurrence on that forum at the moment. Making money was nothing to do with it.
As some people on here know, I used to be involved with Club Polo admin so I know how much work it is running a forum of that size (nothing like running this one which is frankly, a holiday in comparison), any decisions made annoy hundreds of people no matter what is done purely because there are just so many people on there. The admins don't always make the right choices but they are normal people giving up a few hours out of their working lives to try and make it work, not full time politicians with teams of researchers analysing what the thousands of members on there want.
Sorry for the rant but I don't like to see club polo being ruined by scammers and it annoys me even more when people blame the admin for the current state of affairs. Long story short, if you can do better then offer your services because I know they are very short of active staff right now.
