Hi. No you don't need RoboHelp Server to get all that
"power". It is only needed if you want to deploy you help to a
server for your users to access AND to run various reports on what
they use, search for, etc. If you want all this "power" but just
publish it to a website or intranet you don't need RoboHelp Server.
