Default WordPress Registration Page
By default, WordPress comes with it’s own Register page accessible from the login box or this link: http://yourdomain/wp-login.php?action=register
Replace “yourdomain” with your website name. For example, mysite.com
As you may notice, the default WordPress registration page is quite generic, and this RM feature powers it with much needed makeover. The drop down allows you to choose a page which should replace default WordPress register link. Make sure you have a registration form inserted into the page you choose.
