Taking roll with web app

Today I used the web app I created to take roll. It may have taken a few more minutes that just calling out names, but I was able to recognize a few faces. I went student by student instead of down the list, and I ended up missing a student somehow. The web page generates an email I send to myself, and I now have to decide how to record the attendance over the semester. I decided to create an attendance register inside our course offering, so I have to transcribe the attendance data after each class. At least I can apply a status to everyone and then change the status for individual students.
