[opencms-dev] site Registration form and Reserved pages

[Marco]

Hi,

how can I add my web site a "Register to the site" functionality in 
which opencms genarate
automatically a new user account for every visitor who insert his email 
address in a
registration form. So, I need that a user have to register himself 
(herself) in order to visit
some (username/password protected) reserved pages of the site.

Thank's very much in advance!
Mark.
