I know there are very few adverts on SIDC which is a good thing for the forum user, but adverts help pay the bills, as long as the quantity of adverts don't become intrusive and high tech like on some sites.
As a casing point, log on to one of the sites i have joined called adrenalinetrip.net (sorry not a link) but that particular site is terrible for the user with extreme advert intrusion.
As far as not being a member of SIDC, I still show my SIDC stickers on the car and I still enjoy being part of the community and both nationwide and locally even if some of you dislike me which I cant really blame you as am a right pain in the
