Email as required?

The email is one of few fields that needs to be entered.

Ok, I think that would be a nice tricks for a next update.

(In my case) Because if the admin has to enter an adverts for a client who paid Cash at the office, it would be great to don’t have to put a mail but just a phone number.

Thank you for the great plugin.

We were seeking an answer to this also..
Brilliant plugin anyways.
