One of my biggest challenges during this has been training.  I do Sales New Hire Training quarterly as part of a week long, hands on program organized by our Training department.  I'm a big believer that live, in person, hands on training is critical for success, but right now that just isn't possible.  We are investigating MyTrailhead as away to fill in some of that gap.  I don't think it can ever replace in person training, but it can definitely enhance and build on our normal training format and looks like a great way to reinforce topics as well as introduce new features/functionality as we roll it out. #WorkingSafelyTogether
