Matt was very friendly and patient, and solved most of my problems. We ran out of time or we'd probably have solved them all.
The interface (google hangouts) caused some problems. Matt couldn't control my screen, and it was hard for him to read at his end (too small--two monitors). Changing window sizes, and toggling between them, helped somewhat. As a result, though, stuff took longer and ran up more time.
Overall, my understanding of Rails has increased, and my app has progressed toward completion. Thanks, Matt!
