Hello,

 

I would to customize the registration form with following fields:

NameEmailConfirm your emailpasswordCaptcha system

Also the email must be used instead of username in the login form.

 

I know that Community Builder can do it.

I have also find AlphaRegistration component (in the official Joomla extension website), that could do it, but it seems doesn't work with K2.

 

Do you know how can I realize it?
