wtf, neverblue sucks.
In less than a year ive had 3 different AM's with them. They restructure so much that all the AMs either move or quit before you get any sort of relationship with them. The first one sucked but he at least emailed me, he quit. The new chick never bothered to inntroduce her self, and a few months later I had some new guy because she got promoted and he has never said a word to me. I don't bother sending traffic to them anymore.
The only thing I like is their interface and offer system.
Copeac is pretty good, despite the fact that I don't run anything though them my AM still drops me a line on aim asking how things are going and mentions offers I shoud check out.
but top networks are azoogle, eadvertising, ads4dough, copeac, hydra they have been the easyist to do business with and have the best support.
