If you look down near the bottom of the home page, there is a section that lists users who are having a birthday "today". Most names that show up are members who are long gone and no longer active.
If you want to show up there, go to your "User Control Panel" and click on "Profile". You can add your birth date there. Leave the year off if you don't want to share your age.
If you don't want to do that, why not?
