DSL Embedded :: MYDSL ERROR

I'M NEW TO DSL - BUT I REALLY LIKE IT. I WANT TO DOWNLOAD EXTENSIONS. BUT WHEN TRYING TO USE MYDSL, I CLICK THE BUTTON TO DOWNLOAD THE PROGRAM AND GET THE RESPONSE "ALERT" "NO DSL USER ERROR".

HOW DO I GET PROGRAMS USING THE MYDSL FUNCTION? HOW DO I SOLVE THIS ERROR PROBLEM? THANKS!

You must be logged in as user "dsl" in order to install mydsl packages.
