How do small community groups with branches in different areas manage membership fees?
We're trying to form a community arts project whereby people meet up in cafes every week and experiment with different art projects. (inspired by this AskMefi thread actually!
The idea is that we'd start out with one group, then as membership grows, we'll have smaller groups meeting up in different parts of the state/country. Each group would the have its own coordinator, which reports back to the head office. However, we're stuck on how to effectively charge membership fees, especially when the groups start to expand location-wise.
The money's meant to help cover expenses and materials, both for the group itself and the head office.
We have these few options:
a) Charge each person an individual fee that goes straight to HO, then give each group some money
b) Ask for donations during each meeting, and the group leaders decide what to do with the money
c) Charge each group a set fee and let the group leaders decide how they'll raise the funds
d) Have the groups decide if they want a fee and find funding for the HO some other way
What other options are there? How else can we raise money? How have other similar groups gone about this?
(This is for an assignment, but we're given free reign on research.)
