We are limited on what the software that OOF is built on can do.
In the early days, we had no such limits, and it just caused hassle, with an influx of people joining purely to sell their stuff, so we have played around other the years with what is achievable within the software, and what works for our community, and this is why the current limits are as they are.... ....and have been for a few years now, as it works pretty well, allowing potential buyers to get a feel for people by the time they are able to sell.
OOF does cost real money to run. Somebody has to pay the bills. It was started to help owners with their Omegas. It was never started to be a marketplace, and we leave that mostly to the online marketplaces like ebay and co. We are not here paying real money to allow everyone access to place free adverts, though obviously we see the need to bring like minded people together to exchange/sell/buy certain related parts and even cars - but this is for those who have contributed their time in helping others.
Not a perfect world, I know, but thats how we ended up where we are.
No offence intended to anyone, and we know there will always be deserving cases that do not fit, but we have made it a hard and fast rule to ensure fairness and eliminate arguements.
