You can automatically register yourself to be a user of Projects by filling out and submitting this form. Only registered users are allowed into Projects. 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 Projects 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 protected web like Projects 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 Projects. The browser will remember this information for as long as it continues to run, so you can access any document in Projects without being asked for it again.
