User roles are set up to determine what purpose each registered customer will have in the marketplace, are they buying or selling or both?
When a new user first registers, they choose a role. That role defines what membership plans they will be shown until they revisit their membership plan area.
Edit and create new roles by entering title, purpose of the role and if the role is active so guests can choose when registering.
From the registration form, all active roles will appear in the pulldown menu.
