You can automatically register yourself to be a user of [Name of your sub site] by filling out and submitting this form. Only registered users are allowed into [Name of your sub site]. Choose a username for yourself (such as your last name) and make sure this username contains no spaces. Also create a private password. Together these will be your "key" into [Name of your sub site] from now on. This information will be kept in a registration database that is accessible only to the webmaster, not to ordinary users.
One of the main benefits of having a restricted access Web site like [Name of your sub site] is that authorized users don't have to keep typing their names into form fields, such as when submitting an article to a discussion group, because the web server already knows who they are. Similarly, other users can be reasonably sure that you really sent the articles and postings attributed to you, and that someone else didn't pretend to be you when posting.
After you are successfully registered, your web browser will ask you to type in your username and password the first time you try to access [Name of your sub site]. The browser will remember this information for as long as it continues to run, so you can access any document in [Name of your sub site] without being asked for it again.
