WordPress.org

Does this replace the WordPress Plugin that Amember.com sells?

Depends. If you do not require WordPress user group integration, then yes this is all you need.

How do I style the controls?

Here are example stylings for the controls. Place this in your existing .css file and modify as you wish.

input#a_login { background:#F3F3F3; border:2px solid #B4CBDF; color:#333; font-size:15px; width: 95%;} input#a_password { background:#F3F3F3; border:2px solid #B4CBDF; color:#333; font-size:15px; width: 95%; }
