Thank you, Sean. I am using the /shared code to great advantage. In favor of brevity I failed to define my objective clearly. Sorry.
My client wants to know, in addition to who is currently online (/shared/whos-online.tcl), the history of who has logged in, when, how long they stayed (and in time what they did, but that can wait). A summary report of all users (top level) drilled down to detailed reports on each user.
Has this been done by other developers? I do not remember this from my readings or bootcamp. As I write this, I remember something about monitoring usage... I will check it out. Perhaps some other solution is available? Thank you again. -nate
