I am often contacted by non-profit groups looking for a planner to help them find affordable meeting and event space. Community groups should note that Ecotrust is offering Community Grants for just this purpose.
I love that one of the preferential criteria is "Events that are unabashedly hopeful in nature"!
Note that Community Grants cover the cost of space rental only, but not support services such as catering or rentals.
Deadline is January 21, 2010, so get cracking.
