"Privileged" status gives you access to some "friends and family" areas on this server. If you are not a personal friend of the webmaster, you probably do not want to register.
If you register, you do not get the "privileged" status automatically! The webmaster will check your identity and decide. Normally, only people known to the webmaster will be allowed to enter. Other registration requests will be silently ignored.
If you register, please enter your valid email address, so the webmaster could contact you if he has questions, and notify you about the status of your request. Thank you.
