After playing with the system for an hour, I give up.
1) even thou I restrict access to certain users, anyone can still access and download, etc. any file. It makes no difference if you are logged in or not.
2) even if it worked, there seems to be no way to restrict access to a directory. I don't want anyone to even see what is in the directory without logging on.
3) You really have no explanation of the workings of the system, so configuring is at best guesswork, and when things do not work as you think they should, there seems no resource.
It may be a good idea, but it simply does not seem to work and I do not have the time to play with the many setting to find the one that may or may not work. i could never got it to work at all as far as restricting access.
Plus, there needs to be a log off button.
..and then to top it all off when I try to post, can't read the 'security code' and hit Listen, it crashed the browser
