Working on HW 4

I started work on HW 4 today. It seemed necessary to review the lesson on email, so that is what I did, primarily. I also reviewed some information on ReCAPTCHA. Anyhow, figuring out what I needed to review and reviewing the lesson and other info took more than 3 hours, including extra 'issues' that I made for myself. Hopefully, finishing HW 3 will be relatively easy from here out.
