How Does it Work?
Once the site is a "Spintranet", it will now require a valid user name and password to log in. Users gain access by registering on the site. When they register, an e-mail is automatically sent to the site administrator. This e-mail contains two links, one to accept the users registration, the other to deny access. Once a user has been granted access, they can now log into the spintranet and navigate around the site. At this point they don't have any access to change anything on the pages.
The site administrator can now give administrative privileges to each user individually (on a page by page basis). Or they can give full administrative rights to the entire site (not usually recommended). In addition, SpinSite also allows for viewing privileges on a page by page basis. For example, you can set it up so that a few pages are only viewable by a selected group of users (site administrators will be able to view all pages, so usually site admin rights are given sparingly).
