Jan, thank you for the information, now i can understand the difference as to why there is no read me thing...
adam, i did read a lot, my issue is understanding these new levels; Helper, Services Operator, Services Administrator, Services Root.
i am just trying to grasp my head around the terms, what they do exactly.
Sorry, but i am a visual learner since 1999, when i got into a car accident. for some reason i lost the ability to read things and understand them right away, visually seeing how things work is what helps me, and no matter how many times i read the config, it will take me longer to figure it out and learn it, than if someone could explain what the terms mean, cause then i can visually place it in my head and see "the big picture"
