Clearly the ads are a result of our sponsors here at the site. As we've mentioned before, the site is undergoing a face lift right now, meaning there are bound to be things seeming different, albeit an annoyance to some of you. It's bigger and better than ever, so rejoice eh? :jointsmile:
I'd say follow image reeper's advice and get the necessary anti pop-up tools so the ads aren't there anymore. ~
