Hi,
sorry but Easy Profile does not do this natively, anyway you can build a simple plugin that do this, you can also try it in free version, please follow these steps:
- Download, Install and Enable Skeleton Plugin (you will find it at http://docs.easy-profile.com/index.php/article/triggers)
- Open file /plugins/jsn/skeleton/skeleton.php
- remove samples functions: triggerFieldAvatarUpdate, triggerProfileUpdate
- add function like this:

public function triggerProfileUpdate($user,&$data,$changed,$isNew){ 

    $user_id = $user->id ;

    $user_date = $user->registerDate ;

    $data['ALIAS_OF_CUSTOM_FIELD'] = md5( $user_id . $user_date ) ;

}

This code will be triggered when user update/register own profile.
This code will store in field with alias "ALIAS_OF_CUSTOM_FIELD" a simple hash of value that depends from ID and Registration Date of the user.

NOTE: This code is not tested and not supported, this is only for example purpose. You need to have a minimum of PHP knowledges

Hi,
That's awesome... Im gonna try it tonight when i got home.

One last question: Can we disabled editing of some fields? So, user can only edit their profile on selected field only?

Thank you

Hi,
you can set some fields to not be available in Edit Profile page.
