Good point Emma,
Though in this case, it is a small school of about 50 students, so not a lot of work.
One downside of using the SMS that I’ve seen is that many school staff don’t know how to (or the SMS itself is difficult to use) send emails from inside it!
The advantage of using a Google Group approach is that you can allow any staff member to be able to email each class group.
Steve, did the instructions I put in here at the very bottom of the discussion help you?
