I recently started GenAnswers, a free genealogy question and answer community site. It is still in Beta but we already have a number of community members asking and answering questions. The site is similar to sites like Yahoo! Answers, but is focused exclusively on genealogy and family history. GenAnswers members are able to post their questions and help others by answering questions. Along the way, members earn points for their participation, creating some friendly competition.
Please come take a look around. Sign up if you like. Ask your questions and answer questions to help others.
