filetype is always one I use. You use it like this:

filetype:doc finance

doc is the file extension and finance is what is searching for.

http(s):\\*.*@members.”cdgirls”.com\main
The *.* is a wild card of course and everything after the @ sign is the page where you log into. There is a lot of forum postings of porn websites there user name and passwords lot of them don’t work, but you can find some. and when you do free porn. nothing better:) I downloaded the entire site of cdgirls once it was about 60gb.

How can you get in contact with GOOGLE EARTH to get an error in an address (More than 100 miles as the crow flies) Corrected?
I have been trying to get this error corrected on GOOGLE maps for over 4 years with no luck.
