WordPress Login: How to Create a Private Members-Only WordPress Blog & Enroll 1000′s of Users. In this video I demonstrate how to close a WordPress blog to the public and make it available only to members who have a username and password created for them by the blog administrator. The site I demonstrate has 49500 members that I created and bulk uploaded in about an hour. I show the plugin I used for the bulk upload of users. I’ll create a follow-up video in a week or so demonstrating how I used Excel to create those users from a file with nothing but first and last names. If you have need for a private blog/website to share with a few people or tens of thousands of people, this should help get you started.
