I am looking for a way to sell ad space on my forum. Does anyone know of a script that will allow me to do this?
I know that many people use PayPal to sell their ad space. I do know exactly what you want. The easier way is sell ads for a period of X months. You use PayPal for payments. When approved, you place the ad of the customer in the space and pages chosen. I suppose that a script could be better if you sell the ad space to hundreds of people. In that case, people will probably have an account on your website and you could write a custom script for this.
if you use Cpanel hosting with fantastico you can install phpAdsNew and enjoy free of cost its very usefull for PPC and CPM
