This is not suggested but if you really want…
In script version for real estate > 1.6.0 you can in cms_config.php add:
$config['dropdown_register_enabled'] = TRUE;
General customization hints:
First of all you need to read this: http://iwinter.com.hr/support/?p=174
AGENT by default can be registered on that link for example: http://real-estate.iwinter.com.hr/index.php/admin/user/register
If you really want to do this, you can customize default user type:
$data[‘type’] = ‘USER';
$data[‘type’] = ‘USER';
to:
$data[‘type’] = ‘AGENT';
