Client Side Syntax Highlighting
A little while ago, I found a client side syntax highlighting library because I was using blogger. Since I am now using a community server install, I wrote a CS Module that allows you to enter code in a post and the dp.SyntaxHighlighter library will be used when the post is rendered. The previous post here gives an example of all languages supported (Not anymore, since I quit using the js to highlight code, and started using Windows Live Writer).
I know that if you use FreeTextBox in CS then this functionality is already available, but I wanted to continue to use TinyMCE.
Download the module.
