adsense-now(...) is another 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 a 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

For an example of it in use see cwiccer.com, where the Ad appears bottom right within the post/page.
