Ideas from the feedback survey:
Course Material - Rated 5/5
Suggestion - Make sure computers are up to date. Some machines did not have latest versions of Picasa and there was some challenges with how Picasa interprets photo sizes if Regional Settings are metric. Tight time frame - would be nice to work with your own photos and to include scanning.
Instruction - Rated 4.7/5
Suggestion - Improvements around ensuring everyone is on the same page with respect to Windows navigation and terminology. Perhaps emphasize this in the pre-requisites.
