How do I add the add on my site? I don't really get how this site works?

you mean from rozzex.com?

Ok well this is how it works. The first thing you do is register on the site, simple enough. Once you have done that, look at the navigation bar. There should be something called "create an ad". Click on that. There, you should fill in all the required info, such as the forum link, title and description. You done all that? Then you press enter. It will bring you to a screen and will show a frame of your site. If your site doesn't appear, that means you typed it in wrong. Make sure you don't use http:// or www.

After your done all that, there will be displayed two codes. One of them puts it horizontally like this:

http://rozzex.com/ad.php?id=1&site=rozzex.com

and vertically like this:

http://rozzex.com/ad2.php?id=1&site=rozzex.com

You must place one of those on your site. Anywhere you want, I believe. After you do that, check if your ad is activated by going back to rozzex.com and clicking on stats and your site should be displayed if it was worked.

Also remember that if no one has clicked on the ad in 7 days, it will automatically be removed from the ad rotation. In that case, you can contact me or rozzex to get it back in the system.

I hope you understood that.
