I'm looking to add membership functionality to a project and am curious what people out there use.<p>In particular, I'm looking for a simple way to allow members to choose from a selection of plans that I define. In addition, it would provide membership management tools, user flows for upgrading/downgrading/cancellation, dealing with expired cards and other common functions.<p>Doesn't need to do it all but if prefer not to have to write everything myself if possible.<p>Thanks for any suggestions or ideas.
aMember is very good. <a href="http://www.amember.com/" rel="nofollow">http://www.amember.com/</a> . I've used it both as a user and admin on a couple of sites now.
