What exactly is meant by a browser window on the Kindle 2 and how do I reach it? I don't think the Settings & Device Information is it nor can I find this basic (I am sure) information in the manual. Is there somewhere that I can get someone to "hold my hand" and say "OK, glorya, this is how it is done?"

I have downloaded a book from Amazon with no problem but wish to get a few "free" books from links I have found. There is the dilemma. There are instructions on some of these sites, but if I don't know how to access them from/using my Kindle, I am up a creek without a paddle and at the mercy of Amazon and my credit card company. Thank you.
