Yesterday was the second session of my Photoshop for Weavers class, and I recorded the session (just hit the record button) as I did with the first class. After the class, I emailed my students the link to the recording. One of the students experienced loss of connectivity during the class because of a snowstorm, and was able to download the recorded class afterwards. She was so pleased not to have lost out on the class content! Here is what she said:

Thank you so much for recording the class sessions.  I just watched Class 2.  Our power was out for five hours.  A power line across the street from us broke under the strain of the heavy snow.
I'm so glad I did not have to miss out on the information.  Now I have to get to work and put the information I learned to use.

Moral of the story: record your classes!
