Adding AdSense ads to my Wordspress blog

I decided to try to add some AdSense advertising to this blog. As you know, it runs on WordPress which is easily upgradable. I decided to try the All in One AdSense and YPN plugin that I found on the WordPress site. The installation went well, the integration with the blog as well. The ads are showing, but I’m still looking for the way to select where the ads will appear. Now it seems that they appear random, but I’d rather see them displayed at the end of each post.
