What reminders are actually worth
The honest reason to care about this page is no-shows. Between a list of names and the faces in the room, most of the gap is made or lost in the last twenty-four hours, and the reminder schedule is the cheapest lever available: it needs no new audience, no clever copy and no second tool. Registered people already said they wanted the hour; reminders are the difference between meaning it and remembering it.
Afterwards the list keeps the account โ registered, attended, waitlisted, cancelled, no-show, marked as you saw it, exportable as CSV or PDF. If attendance was thin, that pattern shapes the next session's invitation and which personal notes you write. Wording improves; the schedule underneath keeps doing its job.
