How can I add a feature to my site that will allow the viewers to sign-up and log-in? And, how can I make some parts of my site to be viewable only by members that are registered and logged-in?
Common ways to do this are using PHP and a database of users, however, as a word of caution if you do so, you would also need to provide x10 with a way of reviewing this area to be sure you arent breaking the rules.
