I'll stop lurking and add my info, in case it helps someone. My app status is still 'incomplete', and my submitted is 'yellow', not green; however, I have been in contact with a POI concerning intersections of our research interests. I made them quite plain throughout my app. In the emails he kept letting me know how things would be "if I decided to come to Stanford." VERY cryptic. Even when discussing an area that wasn't his expertise, he let me know what advisement with other professors would look like 'should I decided to come to Stanford" or "should I come to be a part of RILE." Could be a way of sounding hopeful? It did help calm some anxiety around the app status though.
