Online genealogy boards are available at Ancestry.com, Genealogy.com, Rootsweb.com and YourFamily.com, among others. Visitors to all three sites can sort the threads on the boards by topic, location and surname.
The message boards are searchable by keyword or name. Some of the boards, including those located at Genealogy.com and Ancestry.com, include sections for members to share information about genealogy software, immigration and military records. The board at Ancestry.com includes a thread for searching cemeteries and tombstones, and the Rootsweb.com board has an option called the WorldConnect Project, which allows users to upload their family trees to the site. Other users then add or edit the uploaded family trees.
