I just learned about this plugin call instamember that (After watching the video) looks very impressive.
Here are some of the features:
Allows you to set up ONE page that ties in with all the different affiliate networks.
Super easy membership protection, and content dripping.
Automatically integrates with GoToWebinar
Ties in with most shopping carts.
Sell products, subscriptions, and memberships
Automate customer service
One-Click upsells or downsells
It comes with a theme, and a resource to get the most out of your membership site.
