According to the website, "They hope to monetize their product by selling their simple communication system to school administrators".

So this chart shows an increasing number of non-monetizable members... and doesn't show growth in their core product / revenue stream: a paid communication system for school administrators.

This situation is very similar to the whole Groupon subscribers issue - which has proven subscribers aren't necessarily monetizable, or a very small / disproportionate members are...

Thoughts on reporting growth of 'users' vs. growth of 'monetizable users'?

Are any users worth anything, even if they aren't related to the core product?

They're demonstrating that users are getting value out of it.

School administrators will pay for this system if they can demonstrate teachers want to use it and are able to get better performance out of their students by using it.

These users are also monetizable - if the system is entrenched in a school or district and they announce free + paid plans they can convert at least some of these to paying users - paid for by the school itself or school district.
