Knowthyneighbor.org
KnowThyNeighbor.org is a non-profit grass roots coalition co-founded in September 2005 by Tom Lang and Aaron Toleos for the purpose of publishing a fully searchable list of the names of people who signed the petition to end same sex marriage in Massachusetts that was sponsored by VoteOnMarriage.org. Knowthyneighbor.org was the first lesbian, gay, bisexual, transgender ( LGBT) group to pioneer this type of activism.
