Unique fields

[aheuermann]

How easy would it be to create an "account number" field in the account module that had to be unique. Is there something in the admin sectin that can accomplish this or woulod custom code need to be written. If so what file would need to be edited. Thanks in advance.

there is a method called create_guid() which returns a unique 36 character long string.
The file is includes/utils.php
