The International Society of Genetic Genealogy exists to promote the use of genetics in genealogy. We would encourage you to check out their website at http://www.isogg.org/ and join the society (it is free!).
The free open access online Journal of Genetic Genealogy is published twice a year and is full of interesting and thought provoking articles which we highly recommend.
The new ISOGG Wiki setup for the benefit and education of the genetic genealogy community has a growing number of helpful topics and subjects to choose from. It can be found at ISOGG Wiki
