This is a place I did not know :(
ConsultantCommons provides an online collaboration space and community for non-profit technical assistance providers to collaboratively build and share knowledge. The goal of ConsultantCommons.org is to provide a resource for nonprofit technology assistance providers to share and develop consulting tools and resources. The system is designed so that consultants can find, contribute and collaborate on tools and information they use to maintain a consultancy and provide services to nonprofits.
Quite young yet. Quite interesting.
