Leave popunders. They make money. Just have the pop trigger when the download button is clickedI am just testing popups, and i think you are right, i have to remove those popups. infact will do that by tonight, i was busy doing some optimizations
Why have you added a massive Clicksor layer ad that covers the whole website. Only reason i was giving your site a try is because it was nice for free users to download from, now its the same as every other site.
