You can automatically register yourself to be a user of OBS.com by filling out and submitting this form. Only registered users are allowed into OBS.com. Choose a username for yourself (such as your social security number) and make sure this username contains no spaces. Also create a private password which is your date of birth. Together these will be your "key" into OBS.com 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 OBS.com is that authorized users don't have to keep typing their names into form fields, such as when doing transaction online, because the web server already knows who they are. Similarly, other users can be reasonably sure that you really made the transaction and any money owed to you, and that someone else didn't pretend to be you when online.
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 OBS.com. The browser will remember this information for as long as it continues to run, so you can access any links in OBS.com without being asked for it again.
