Two days ago discovered a great plugin for making a site private. I was looking for something where one can set up members oneself, without opening the Website for everyone to register.
The Jonradio Private Plugin works perfect! I get to set up the member in WordPress, and it then sends an e-mail to the user to set up a password. One can choose different levels for membership. Subscriber is profile only. Contributor can add posts and edit the posts the contributor added only. Then Editor can add all posts and pages.
Here is a link to the plugin:
