How many people should I invite to my first Malairte meetup?

Four to eight people is the sweet spot for a first meetup. Small enough that you can answer every question, large enough that conversation flows without you carrying it. Invite ten and assume two will not show; that is normal for any free event. Resist the urge to scale up early. A meetup of six attentive humans creates more long-term community than a room of thirty distracted ones, because each person leaves with a wallet, a question answered, and a face they recognise next time. After your second or third successful small event, you will know which attendees want to help host the bigger one. Build the regulars first, then grow.
