My site is addressmunger dot com. I have three unused spots on the right in white that say "Your Ad Here". All the older pages are PR3 or PR4. I have created three new pages, so those pages do not have a PR yet. The site is generally for web developers, but contains the following pages: 1. A javascript and css address munging tool 2. A tool to convert characters to ascii so that code can be displayed on a website. 3. A contact form generator script. 4. Two pages of ASCII tables containing the ASCII codes for the standard characters, and many more nonstandard characters, your computer can display 5. A list of frequently asked questions 6. A javascript minifier and obfuscator 7. A mailto syntax tutorial 8. A password hashing tool 9. A list of recommended products 10. A list of keywords that I use for predeleting spam 11. A spam related glossary My traffic is the following: http://extremetracking.com/open?login=addrmung How much should I charge for each of those links?
