I don't believe they are accepting US affiliates. I signed up months ago and it took them a month or more to turn down my application. I had a quality site set up as my URL and my stats showed that they didn't even seem to visit. I also tried to signup under Pepperjam and they still haven't approved or declined me.
friend just got denied... they ran a regular blog. don't know what epn is using for criteria.
revisited this idea because of it. epnStore - doesn't require signing up for epn - works off one account w/ epn w/ unique campaign ids. rough on the edges right now. hope to clean it up.
I just got denied too. I had a blog with only a couple posts, but one was like 600 words and really good (at least I thought so). No ads either, and I still got denied.
Don't apply with thin sites or BANS. It was a long discussion about getting approved to epn. So you better spend some more time expanding your blog/bans site whatever to get accepted...
