I'm using program with a Create Account Page. It asks for User Name, Password, Email Address etc., I want the User Name to be the Users Email Address, is there a way to combine these, so that the User Name is the email address?

I'm not to familiar with code or values, but User Name shows:
value='<?=$account->user_name ?>'>
And the email address shows:
value='<?=$account->email ?>'>

Is there any way to combine these?

Thank you. Here is the code:

<?php global $account; ?>
