Instead of asking for both an email and a username on registration, this plugin lets you ask for email only, and uses that as username as well. Since the password is automatically generated and emailed to the user, this allows for sign-up form with a single form field: email.
For users that registered with different username and email address before this plugin was installed, their username and email address will be interchangeable on login.
The plugin offers a shortcode, [NP-registration], to add the registration form to a post or page.
Note: This plugin has not been tested with WP versions older than to 3.1.5. It should work with some older versions, but we can not guarantee it. However, if you are running an older version of WordPress, there are some very compelling arguments why you should consider upgrading. If you need help, there is plenty of free help to be found on WordPress.org, and Next Page, the authors of this plugin, offer a paid WordPress maintenance service.

This simple plugin gives you the wonderful benefit of a really simple signup widget for your WordPress site to allow you to accept signups to your blog. The signup works over AJAX so no leaving the page. Registration attempts are responded to with a confirmation or error message. All input is sanitized and validated using native WordPress methods.
Those who register will be added straight to the subscribers list and given a randomly-generated password (which they can change via WordPress’s password recovery if they choose).
This is great for exporting the list for use on mailing services like MailChimp or in conjunction with another WordPress plugin to update your subscribers via email.
The widget is marked-up for Bootstrap 3 and also utilises a Font Awesome spinner icon although you can apply your own CSS as desired and these packages are not required.
You can set whether to accept a name along with email. If you opt to hide the name field then the username will be derived from the email address.
