This plug in is so simple to use. Basic copy and paste for AdSense. If you use Chitika ads, this is fully integrated in so you can generate the code directly in the plug in interface. Supports multiple ways to place ads- including widgets. TONS of widgets, with one widget that selects from the ones you set up in the settings page.
Great plug in and a no brainer for those of us too lazy to fool with code, theme files and all that good stuff.
