I've been using the "All in one adsense and ypn plugin" for over a year now.. I like the fact that it can put "adtest = on" to the adsense code when I vew my website while logged in. Since I'm an optimization freak, Im constantly tweaking something or the other on my website and it helps that impressions are not counted.

The plugin however, does not allow me to set an ad unit at the start AND at the end of a post.

I've tried a ton of other plugins but none of them have the "adtest = on" option.

Any ideas?
