It looks like I have a couple repeat attendees in my next class. I'm hoping that's more of someone in a company deciding that this was a useful training experience and sharing that with other people they work with and just re-using the same attendee information and not people failing to realize that they signed up for the same class twice. It's not uncommon for people to decide they want to re-take a class from me, but that's usually 4-12 months later, not 1 month later.
