Adware Adware Adware Beware!!! I have used them and they do pay pretty well. I was impressed. Although I believe you will notice a traffic loss because so many people hate the annoyance. Once installed you will notice constant pop-up ads, an annoying search toolbar, miscellaneous junk in your add/remove programs and a heck of a time deleting and repairing registry.
I did register with them and they didn't accept me yet .. Its been 24 hours .. I want to see how they will look on my site ..
Give them time... they need to carefuly review each member so they do not get in trouble. If you are looking for some way how to implement zango at your site than here is nnice article: http://www.payperinstall.org/make-money-with-zango-gateway.html
