Using the user defined menu, you need a privilege and a way to access it.
Each menu you create defines a new privilege. You must grant this privilege to co-administrators.
User defined menu may be used either from the the command line (text or GUI) or using the web (HTML). Web user can connect directly to the menu using the following URL:
http://your-server:98/htmlmod:usermenu_ID/
where ID is the menu ID. Using the GUI or the text mode, one may access the menu using the following command line:
linuxconf --modulemain usermenu ID
