One question and one mistake

When doing the lessons for beginner do I have to be standing up as I enjoy playing the piano while doing the exercises which I sit down for, nice and relaxed.

my mistake I've made is I accidently cancelled my free trial is their any chance at all I can get it back, I started today and I feel like a fool 

Standing is preferred for your best posture and support; but if you're seated, sit on the edge of your chair so your feet are on the ground. Keep your spine long and be careful of the tendency to reach your chin forward or roll your shoulders forward. We want to be just as energized and tall in our seated posture as in our standing!

Okay thank you, I sit like that when playing piano anyways I'll make sure to be careful 

Sounds like a plan, Cameron!
