adsense-now-lite is a Google AdSense plugin by Manoj Thulasidas.
It’s simpler than easy-adsenser. It provides the ability to place a Google Ad in up to 3 places in a post, each in one of 3 positions – left, middle and right.
You can disable the one’s you don’t want.
As with Easy Adsense you have to cut and paste the code generated by Google AdSense
