Can members register for free?
Free/Open Registration (Enable/Disable)
s2Member can lock-down all registration forms provided by WordPress and many of the most popular plugins/themes for WordPress. In this way, only paying customers can get an account. Or, you can choose to allow Open Registration; making it possible to acquire Free Subscribers that might later become customers by completing checkout and upgrading their account to a paid status.
Free/Open Registration with Pro-Forms Requires s2Member Pro
s2Member Pro makes it possible to allow Open Registration using Pro-Forms of your choosing—even if you don't intend to use Pro-Forms or a payment gateway. Free Registration Pro-Forms can be used to acquire new users (regardless of your global Open Registration setting). They can also be used to configure a specific Membership Level, CCAPS, trial period, and more—specifically for Free Subscribers, and based on a specific Pro-Form instance. In this way, it is even possible to offer paid Membership Levels > 0 at no charge whatsoever, and maybe for a limited-time only.
