Also, great name. I've seen others in this space with names that aren't quite as clear as yours, which is important for the demographics you're targeting – teachers and parents.
I really appreciate you forwarding it to them. If they have any questions at all, or just need a walkthrough, they're welcome to email me: m [at] classpager.com.
There may need to be some customization of the analytics to handle their larger classes, which we're open to -- we've basically just been building features based on the requests from our teachers.
Feel free to pass on my email -- m [at] classpager.com -- if the teachers/professors have any questions.
