Hm ... no, it's not what I want. In this case the username is still used - and given to the customer. And he has to use it to log into the account. I want to remove every (!) hint of a username in it's classic (visual) style. The customer ONLY should know and use his email address as "username".
I know this is a basic Joomla issue - not Hikashop. But hoped there could be a good solution. However ... as I wrote before my workaround is good enough for the moment. It's not that elegant but works.
