Adds an activation code to the new user email sent once a user registers. The user must enter this activation code in addition to a username and password to log in successfully the first time. A 10 character activation code is added to the user meta when the user is registered. The administrator may reset the activation code or enter a new one from the users profile page. This plugin does not currently work with multi-site. Multi-site uses an activation key system for new registrations already. Spanish translation by Andrew Kurtis of WebHostingHub.
