Just a basic list of ways you can help and links to those pages (Partner, Join, Donate, Volunteer)..
In my understanding:
Partner is a business, normally larger donation ($1000 and up?)
Donate is private citizen or smaller donations
Volunteer is to help with cleanups, events, etc
I also thought about volunteer your business (not the same as partnering). What if someone has a restaurant they would host a gathering or cleanup at, or a company would like to loan a vehicle, etc?
