When people start to come to meeting regularly they are known as attenders. If, after a while, they find that they wish to become members they take the extra step of requesting to join our meeting. Their request, in letter form, goes through various committees and the meeting decides whether or not they should join. If so, they become members, and if not they remain attenders.
If a child's parents are members, he/she is made a Junior Member of Meeting at the parent's request and when he/she is approximately twenty he/she can join officially.
If a member of another Meeting comes to our Meeting (because he/she moved etc.) he/she can have his/her membership transferred.
The reason people become members is not only to show their spiritual committment to the Meeting (though that is part of it). There are also special rules. For example the clerk of our Meeting must be a member. There are also some committees that only members can join.
Attenders are welcome to stay attenders as long as they wish. Becoming a member is up to each individual.
