Why are they so many post about ads problems these days.........!!!! Ppl should search more! BTW is that link should be placed in a sticky post somewhere, that is easy to see!!
Can you be more descriptive? Are you talking about the x10Hosting Ads? If so, then go http://www.x10hosting.com/ads.php. You can place those in HTML pages. If you need to put the ads in PHP pages (most forums, etc) then search the forums then post here if you are still having problems.
