Affinity and Support Groups must be open to any temple member who finds an affinity with the group, and must be advertised to all members. No fees will be charged for participation. Other than for same-day use, donations collected to cover the cost of activities, materials, or food will be deposited with the temple and receipts submitted by the organizers for reimbursement. All activities sponsored by an Affinity or Support Group must be related to its purpose.
