The plugin can be run without using the registration forms.
For users that might have some other method of registration, up to and including private blogs that don’t want anyone registering and thus sending invited users login information. In this case, complete the following based on your specific setup needs:
- Uncheck the options to display registration in Options > Content > Show Registration Form.
- Do not establish a registration page for the plugin (shortcode [wpmem_form register]), and make sure Options > Pages > Register Page is unset.
- Add the register=hide attribute to the [wpmem_profile] shortcode.
This is not the same as turning off registration for WordPress itself. That is a separate issue. This is simply a setting to remove the WP-Members registration forms from display.
