I was signed up for the basic glass bead class with Sean last week that was cancelled. I was also signed up for the following week’s advanced class. I see that one is the prerequisite for the other, so I should cancel my reservation for today (10/18, 6:00). However, I don’t see any way to do that!
I think it works this way – if you’re signed in to the Calendar, go to the “My Account” button on the top right of the screen. From there, pick Attending Events. Click on that, and the class, and it should give you the option to cancel.
