On my teaser slide that I placed on the home page I said “What I learned while teaching 4500 people to use Salesforce”. Let me add this disclaimer: I was not alone on this project. The thought of one person taking on that much work is laughable. There were three of us at first, so it was a team effort. You can see that the student-teacher ratio is now much lower at a more manageable level of 1500:1. 🙂
