Coordinated Crowdsource Protocol

CCP is a  way to supply group events that distributes the burden of buying and bringing the supplies, and centralizes the planning. It can be thought of as similar to the Pot-Luck Protocol, except with more direction and administration.

M.O.:
1. Coordinator(s) create a master list of suggested and preferred supplies.

2. Coordinator(s) share the list with participants.
Ideally this will be via some convenient interactive system such as social media.

3. Participants volunteer to bring items.
A process known as "calling." Called items can be either from the list or write-ins.
This allows people to bring items that are easy for them or that they already have.

4. Coordinator(s) assign remaining items as needed.
Assignments can be given to late-committers who want to know what to bring.
