Progress report: how's everybody coming along in the PDC?

Hi everyone! I've recovered from my illness (was just a terrible cold really but it lasted weeks and I had total brain fog) and am hard at work getting the rest of our classes published in the certification course. How's everybody doing? Once everything is published I'll go back through it all from the beginning with fresh eyes and do some editing. Let me know if you felt like any areas were confusing or redundant or if you want more details somewhere!
