Add membership ability!

If someone sells or gives away their dog, is there a way to transfer it to a new owner?

I would like to make it so my clients have to have attended one class/event before they can sign-up for another.

It would be great if we could setup automatic reminders for the upcoming session?

We would like the clients to be able to cancel their private training registration online. We would also like a number of days before to allow them to cancel.

We would like to be able to enter a percentage for each instructor to be used in the Trainer Commission Report.

I would love to have the session number displayed on my calendar for classes.
