Checkout email

Found this here on the forum.

"You are using an email address which was already used to create a joomla user account before so it cannot be used for "no registration" checkout."

Understand it.

My question is, is there a work-around. Or, if users register through the Joomla registration after Hikashop is setup with No Registration is this a non-issue?

Naturally, I have people who need access to the backend control panel who will want to order something as well.
