Can a host add students and/or businesses manually?

There is not a way to add students manually, they must register their own accounts, but there is a way to add businesses manually. Students can register their accounts through either an email invitation or through the Landing Page link. In order to add a business, go to the "Businesses" page and click on "Create Business." After you do that, students can either request to join that business or you can manually add them to it after they register their account.
