Best free membership plugin for WordPress IMO

Short review: Just install it now!

Long review: From well-written to well-documented code to many great tutorials, and from frequent updates to a very responsive and friendly developer, I can confidently say, based on my own experience, that this is the best free membership plugin I’ve found so far. I’ve researched and reviewed (almost) every free members-related plugin out there, and this one just beats them all hands down IMO.
