At the onset I found I needed to review the video tutorials many times. This helped me get through some mistakes I made in setting things up. The support is very timely and new upgrades keep the software user friendly.
Not all my parents use e-mail, not everyone checks their e-mail regularly, but after two years I have found that this software has helped communication between parents and myself greatly.
This summer I started encouraging online access for each parent. I assigned Usernames and Passwords and allowed them to register for open slots. As Fall approaches, my schedule will be set but I will have a few open slots that can be used if they must cancel a lesson.
