I just got approved into Peerfly yesterday. I always used to work with other networks but now I applied there and all I can say about them is "WOW!".
The first thing I loved about it when I logged in to my account is their dashboard, it is awesome, you can find everything you need and it looks cool! There is even a live chat box in the left bottom side where you can talk to your AM any time you want, and if hes online, he answers in seconds! I told Luke that I would like to have him as my AM, but they approved me before he could even read my e-mail. They're quick as hell!!!
The other thing I very like there is they have a huge offer range with quality CPA offers, you can even categorize them by your preffered traffic method.
I'll start to work out a bunch of campaigns with them next week, and I may share some case studies with you about promoting Peerfly's CPA offers.
