For those with e-readers

If you are like me and are looking for a way to manage the PDF's you have downloaded, check out: http://www.a-pdf.com/infochanger/download.htm

it allows you to change the author, title, subject, and keywords in the PDF file. Though it won't let you do it to encrypted files.

To un-encrypte files, i used: http://www.sybrex.com/products/gui/protectionmanager/download.php

it is a trial version, but i was able to take care of a large number of encrypted files with it.
