You now have the ability to become a site member without revealing your membership to the outside world. Setting the "I'm shy. Make me invisible" button on account creation or through your profile (the 'My Account' menu item) will hide your profile details from public viewing, yet still make you a fully qualified member with access to all of the site member features.

Please note that regardless of your invisibility setting, active participation in chatrooms, forums, or weblogs will tend to reveal the fact that you exist.
