So I've been all over the internet searching this topic and have had no luck finding the answer.

Using Web Designer Premium can I add in a user registration function to... A) allow access to user-specific pages apart from the pages of the main site...B) To allow admin level registrants to make edits and changes to images and text on certain pages


The concept here is to have a main "Franchise" website for all to see and then have "franchisee" sub-domains that allow the franchisee (once logged in to admin account) to customize images, products for sale and text on their sub-domain pages...Is this possible? and if so, How do I accomplish this?
