Content-based sites with paid memberships

If you've ever wanted to create your own content-based web site that requires paid memberships, now you can do so easily with Ruby on Rails, Radiant, and the Content Management Rails Kit.

Built on the same recurring billing code used in the Software as a Service Rails Kit, the CMS Rails Kit is an extension to Radiant that enables you to have various paid or free membership levels for a content site. So you could easily implement a pay wall for your content, or simply require registration to access it.

Information may want to be free, but that doesn't mean you can't try to charge for it anyway. :)
