This newsgroup doesn't seem to get a lot of traffic. Are there any web
forums that somebody could point me to that deal more with grabbing
unsecured Wifi or cracking WEP networks for free internet?

Also I need to learn about how vulnerable my computer is on such a network.
I've turned off folder sharing in the main areas but probably I've missed a
few areas.

I'm new to this. I don't want to start downloading massive amounts of files
because that will degrade the connection. Just light web surfing - mostly
text based - that way I'm not interfering with the quality of the
connection. Hopefully that will make it less likely that the owner will
lock it down.

Also I was wondering if people often set up unsecured networks in order to
entice people to log in so they can snoop on what these freeloaders are
doing? Can the owner of the router know each website or newsgroup I go to?
What about keyloggers? Can they retrieve passwords?
