Hi
When a user (customer) with the same email account wants to refill the form on another subject, it gives a duplicate user error.
(Hey emails are unique and they cannnot be duplicated, we are using WordPress's users table to store customers, so WordPress would also not allow this to duplicate the email. Better you login if you already have the customer account. And also request quote do not give you dupilcate error if email is found, it asks you to login. Which is very relevant message.)
There's no need for that to happen. A customer can fill out the form for more than one subject.
Also, we do not want customers to connect to the system. this is not necessary. how do we solve this?
---------------
To keep the identity unique we need something at least to identify the customer. Like email is best way in this platform to keep the customer unique. Names can duplicae.
