Me neither! I'm glad I had an ultra-geeky type person install all my network stuff back then. He explained to me that I should stay away from anything public, not safe at all. I didn't understand the warning back then but, I surely understand it now.
I too have one of those little modem thingies. How secure are those? I've only used it once or twice. I bought it for emergency purposes. I'm rarely away from the core systems. ;)
