Hi everyone! I'd love to add my website to the list, it is called Kubizo:
http://www.kubizo.com. There are three sections:
1)
How to change Kindle screensaver, including an automatic application that installs the screensaver. You do not need to fumble with hacks
2) A gallery of
Kindle screensaver pictures
3) Coming soon (still working on it), a
Kindle screensaver generator
Thanks everyone!
