I just finished up my first plugin for b2evolution. It adds the Google Analytics tracker code to the <head> section of your blog. Simple really, but there's some quirkiness to b2evo's plugin system I wasn't thrilled with. I'll save that rant for another post. If you're using the latest version of b2evo and use Google Analytics, feel free to use my plugin to add it to your skin instead of hacking the skin.
