In a process called the gift circle, everyone shares their needs eg. need dogwalking, editing help, haircut etc. Then others can volunteer to help them without barter or money being exchanged. Over time this builds a community as everyone helps everyone. https://opencollaboration.wordpress.com/2009/11/28/gift-circle-faq/
