Actually, we setup a page on Google+ for the GPWA quite a long time ago. But we never created graphics for the page or announced that the GPWA Google+ page exists.
Finally, at long last, we have prettied up the page, and are now publicizing its existence.
If you add the GPWA Google+ page to your circles, we'll add you back. I've just added the 100+ folks that already included the GPWA in their circles.
