I currently have two separate websites with separate domain names. I want to create a splash page so that visitors can go to either website but there will only be one domain name. Basically, this will require require the two websites to be under one domain name and the visitors can choose from two choices - "Students" and "Instructors". The students and instructors will be able to create a login and password (this feature currently exists) and go directly to the content. On their initial visit, students will be required to purchase the online textbook prior to proceeding to the content. I would like a "Buy Textbook" button and a WooCommerce shopping cart feature added so the students can purchase the textbook prior to creating a login and password.
