Riot, you know who the site owner is, he introduced himself when he took the helm. Instead of posting multiple threads on the same subject, how about getting in touch with the man upstairs and discussing it directly with him? Maybe if there are enough people asking for the same thing he will consider granting your wish in one form or another. But if it's just you and a few others, I don't see it happening any time soon - having paid memberships opens up a whole different can of worms, which the site owner simply may not be willing to deal with.
And I still fail to comprehend what the big deal is! All I see is a single thread at the top of each forum, and that's it - there are no annoying popups, no ad shown as a post at the bottom of every page of every thread, nothing of the sort. IMHO this advertising ya'll are complaining so much about is about as subtle as it can get, you just don't click on the thread title at that's all it takes to not see it. You wanna see bad, install the Ghostery browser add-on and go to a higher-traffic site - for instance on one of the most famous offroading boards my Ghostery comes up with 12 blockable trackers most of which are advertising, now that's some pretty heavy stuff right there. In comparison here we only get 2 blockable items which are the Facebook widget and the Google Analytics, both of which these days seem to be just about everywhere on the internets. So you see, we actually have it real good here, and it seems to me the site owner is allowing just the bare minimum to keep up with the bills to keep the site running.
