A DigitalPoint Forums thread spots a third new Google AdSense feature for today, this one is called "My Publishers." It is a new tab added to the top tabs of the AdSense console that allows you to search for "my publishers." This was reported over at Media Vipers and he has some screen shots, I have cleaned one of them up for you.
You can see that it is a search form that allows you to search by email, company name, contact name, client id, association date and country. Very interesting screen...
The URL to get to this page doesn't work for me, but it is at https://www.google.com/adsense/dev-search-publishers.
I am not sure how this will be used exactly. Maybe it will be for a new breed of consultants, those that manage Google AdSense ads for publishers. I guess time will tell.
