FLOSS Foundations spawned off a software project (of sorts). If you are interested in software systems to help in the management of non-profit organizations, join the Foundations Software list. The FSF Wiki on non-profit management software may also be of interest.
The face-to-face meetings are a place for the people who try to Get Stuff Done at various open source projects and non-profits around open source to congregate, share information, and pick each others' brains. This year we met July 19th and 20th in Portland, Oregon (USA). The meeting will be held immediately before OSCON, at the Oregon Convention Center in room D132.
