Thanks for the additional information,
Jun! Well, I installed Tor last night but the Tor-specific Firefox 3.18 "portable" browser kept giving me trouble: It would tell me an updated version of the browser was available, but when I'd install it another dialog box would inform me I was no longer connected to Tor. Plus, it would uninstall my Firefox 5.0 browser and install the (apparently) non-Tor Firefox 3.19 "updated" browser right over it, even though I'd put all the Tor stuff on an entirely different disk drive. Hmm.

After three of those go-rounds I decided to give it all a rest. Maybe I'll give Tor another shot tonight. (The Darknet only works at night, when it's dark, right?) But seriously, I shall heed your advice and exert extreme caution if and when I dare enter The Realm of the Darknet!
