s2Member is one of the most robust, flexible and simple membership plugins available for wordpress.
I currently use it on at least 4 different websites that manage from 20 to 3500 members.
You CAN use it free, and for a lot of uses that’s sufficient. But the PRO version of s2Member offers some really helpful tools that make your learning curve shorter and and your options more versatile. One of the many extra features you get with PRO is easy ClickBank integration!
s2Member works very nicely with Buddypress to give you a very smooth and simple user experience… out-of-the-box you can be up and running in less than 30 minutes.
With s2Member, you can:
- protect and drip content to 4+ levels of membership (you need PRO for more than 4)
- automate your signup and payment process (free allows for Paypal Standard, you need PRO to use authorize.net or Payflow Pro from Paypal)
- automate your renewals
- control access based on membership level
- offer one-time-only sales incentives to members
- offer internal upgrades and other bonuses
- integrate easily with your Mailchimp® or Aweber® mailing lists (others, too… I’ve just only used those two)
- and more…
[updated October 2015] Still using s2Member on a few websites with great success. We are available to help you with implementation and customization if you are finding you don’t have the time or inclination but need the tool.
