competeservices.com emailed a newsletter about this. They said you should take them to court for what you think the student is worth. That's advertising and everything. I will look for the newsletter because I save them all and post it. Good luck and don't allow to much contact with your younger students and keep her away from the studio business. Never let your guard down because all though you don't want to stop anyone's way to make a living you don't want to just hand your business over to anyone either.
