I'm going to create a 2 WordPress membership sites (ideally using Genesis theme but I'm flexible on that). I would like to offer the membership site to affiliates to promote.
I would like to use WishList Member as I've used it before and it is super simple. The one drawback of it is is that is doesn't accept affiliate payments, ie. there's no ability within WishList Member to pay affiliate commissions to your affiliates. Apparently you have to tack on a different payment gateway in order to get that functionality.

Has anyone done this? Are there other membership site plugins for WordPress that offer an affiliate payment scheme?
