The person who says “I’ll text everyone the plan” and actually does it is quietly running the whole trip.

Groups run far less on authority than on whoever is willing to do the small unexciting coordination. Sending the time, the place and the meeting point removes the uncertainty that otherwise keeps ten people half committed. No title is involved, and everybody follows anyway.

Be that person once this week and watch how fast it works. One message with the details, sent early, no discussion needed. If you want more influence somewhere, this is the cheapest way in.
