I would suggest you rethink wanting to join EWA. There are currently 2 threads open showing how Ryan Eagle tries to fix offer payouts (across affiliate networks) so he can maximize his profit. He or someone he hired also hacked another leading affiliate networks AIM account and started spreading false rumours that it's closing down. I'm not sure I'd work with anyone who had to resort to those dirty tricks to get ahead.
just say you're killing it with PKM's offers and you wanna run with another network for some of your 'shadier' methods. EWA's cool with that as long as you email them beforehand
EWA does not have the highest payouts... tried recently c2m is paying 5.25 ewa pays 3.75....contacted rep best they could do is 4 something even with volume.
