Hello, 

I already registered my students and myself: 21 in total. 

Do chaperones have to pay for the conference?

If so, how do I add on the chaperones to my list?

If I chose the masters class for myself, how I change that? (I have to take care of my students instead)

Can I have the invoice for 23 people (or 21 if chaperones do not have to pay)? I already have the PO ready.

Thank you.
