This Wordpress plugin gives you an easy way to integrate Nanacast.com with Wishlist Member.
Whilst Nanacast provides it's own fantastic membership area, it's hard to go past Wordpress for ease of use and available templates (like OptimizePress)
And Wishlist Member is one of the most popular membership site plugins around for Wordpress.
I wrote this plugin because I needed to get Nanacast talking to a Wishlist-enabled site. It is heavily based on the Memberlock plugin provided by Nanacast.
Hope you find it helpful!
