I tried it on one of my sites but was frustrated by two things. They have this fancy ad customization form where you can select the font and color of various ad elements but I just couldn't get it to underline the ad links/titles so that they look like links to web surfers.
The other problem was that I noticed it was showing casino ads and that wasn't something I felt comfortable promoting so I took the ads off.
Any company that pays with E-gold I would not feel good about. Esp when they will not pay out via Paypal or Company Check... Don't put to much weight in that though it is just me speaking at 550am hehe
Actually they're paying via e-gold is their best feature. Paypal only fully supports 28 countries so other payment methods like e-gold are the best option for those of us not living in a paypal supported country.
