Who wants that guest to join? Everyone! Who knows how to join? You do - and not the guest. We must be very clear in stepping them through the process of how to join. Aside from conversations in the meetings and the guest kit, this is best done via email.
Have a templated email that is sent to a guest soon after their first visit that thanks them and outlines exactly how to join, the benefits of joining and attaches the documents they need (membership form and schedule of fees).
Have a templated email for after a guest visits a second meeting which is similar but adds a little more suggestion to joining as a member to get involved
Have a templated email that shares with a new member what the induction process will be like, when they will be on the agenda, and the club’s handbook of meeting roles
