I really can't understand the logic of paying for information freely given by others. I thought fora were for like minded individuals to share, freely, information on a common interest. So, if I want to post a site that others might find useful I have to pay for the privilege. Similarly if I want to find a site. Seems to contradict the whole ethos of the forum, which, after all is only as good as its members.
Seems to me there are two options: someone sets up a new forum which is dedicated to sites (the rest is "froth") or move over to Motorhomefacts, where as long as you contribute a site you have full access to the interactive map.
