This easy-to-use WordPress membership plugin is a more robust solution than the previous two options. It’s the most powerful membership plugin I’ve seen, offering a much higher level of functionality than its competition.

The downside is that MemberMouse has a monthly fee, unlike the WishList Member and MemberPress, which only require a one-time payment (unless you want updates and support for more than your first year).

However, I’d like to point out that if you run a successful paid membership site, the cost of your membership software should be covered each month anyway.
