1. Multiple Inactivity rules.
Day 3: You haven't logged in yet - 1 time. After they log in, this is never activated again.
Day 3: You haven't logged in in 3 days - A reminder for every time there is a (defined) period of inactivity, only activated after they have logged in at least once.
2. I would like to be able to send out a custom notification if class is less than X% completed by Y time (Time = after enrolment, or a specific date).
