When I create a Meetup, I like to explain what the ride will be, and how I’ll conduct it. The “Message Your Group” box only allows for a few sentences. It would be nice if that was much much bigger.
I agree it would be nice for the group leader to be able to post larger messages, when I join an event I like to read what the group leader expects. Add to that a list of stored ones would be cool, eg “Slow down at the front”, “Keep the grouping” etc.
