As you know, Google is switching many of their help forums from Google Groups to a new interactive help forum. The AdSense forums, Chrome forums and now the AdWords have all moved over.
AdWordsPro Sarah had the honor of posting the last message in the Google Groups forum. The new AdWords forum is over at google.com/support/forum/p/AdWords. In honor of the move, she posted the latest tip, Where Are My Clicks Coming From? Using The Geographic Performance Report.
I also wanted to let you know, after a couple days of research, I found a way of tracking the threads at these forums in a semi-efficient manner. Not as good as the old way, but it will work for now. So, we got you covered for the new forum and tracking the most important threads at these forums.
