Wow! Thanks for the speedy reply Randal! :-)

I *think* I understand what you're talking about, and the usersonline script
that I mentioned above does have a default time of 15 minutes:

#The number of minutes the user is assumed to be online after a hit. (
+default 15)

$minutes = 15;
[download]

However (for whatever the reasons), I'm unable to get the script to work...
I do have SSI and have followed the install directions as faithfully as I know how (twice now!)
anyhow...

Thanks again Randal,
