I created and maintain 3 wikis:
http://relocalizesacramento.wikispaces.com open format so that Sacramentans can add sustainable tips, events, reports and news.
http://shoc.wikispaces.com is used as a website for Sacramento Homeless Organizing Committee and features info about SHOC and local homelessness news, links, events and action items.
http://homeward.wikispaces.com features Homeward Street Journal archives of locally written articles that have been published in the paper
