Can one of the clones please clarify what actually happens when we click on an ad, with regard to benefits for Mudcat? Does it mean that the site gets some actual per-click revenue, or what exactly?

Like several of the others above, I have the forum bookmarked so I always bypass the home page, but if I can help out the Cat in some tangible way by following these links, I certainly will. But I'd be glad to have some idea what actually happens when I click, apart from acquiring yet another cookie.
