Finally, we can change the code directly from google adsense account! I tell you, this is one of the best moves that adsense made. Now it is a lot more simply to edit our codes. No more logging into our hosting account from our multiple websites, looking for the code that we needed to update. Now we can simply edit it directly from our adsense account.
Just make sure you name all the ad blocks you create so that you don’t get confused when you need to edit them, and if you have a lot of blocks. 
The negative aspect is that if you make a mistake creating the block with the wrong size them you can’t delete it or edit the size…. (at least i haven’t find it), i already have one useless block….
This is just my little update on making money online with google
