Terriamn, I don't know you yet, and I'm completely confident you'll have no problem. I've been sewing nearly my whole life and every unfamiliar machine scares me. One scared me so much I hardly used it for 6 months. Once I calmed down, I enjoyed it like all the others.
I never worried about user classes until the ones with built-in computers showed up. Now I'm thinking of retaking the classes for my newest that I've had for 18 months just to review some of the advanced features I've forgotten about! It's amazing how much info they can jam into a 2-day class.
Now if someone had classes on smartphones, I'd be first in line there too! lol
