with other members to ensure the information provided is as accurate as possible. When it comes to disputes over what information is correct, any sources that are provided are used to find the definitive answer. The community developed a conflict escalation process to help with the resolution of such disputes. Recognizing that in some cases this openness can lead to unwanted and unwarranted additions to the global family tree, the volunteer leaders at WikiTree have created procedures for working with two special categories of ancestor profiles. Members must pass a self-evaluated quiz to edit profiles of persons whose birth year is from 1500 to 1699, which includes most of the early colonial period in the Americas. Members can “pass” this test by demonstrating they have read the WikiTree source and editing guidelines. As of January 2016, a more stringent evaluation, based on a member's demonstrated genealogical experience and ability to work cooperatively, is now required to edit profiles of persons born before 1500. This process attempts to strike a balance between open and collaborative editing and the desire to strive for historical accuracy and credibility within the genealogical community. Features The WikiTree site emphasizes the building of a shared, worldwide family tree. Members do not maintain individual trees, but instead contribute to a single collaborative tree. The site's goal is to have one profile for every person, whether living or dead. Duplicate profiles are merged and the information is consolidated, connecting different family branches in the process. The site maintains a page of “frequently asked questions” (FAQs) and a “genealogist to genealogist” (G2G) forum that allows users to get answers and help with both genealogical and technical questions. Points and badges are awarded to members who answer questions and contribute information to the site. Additionally, the site is managed by a team of volunteer leaders and mentors that serves the community in a variety of capacities, in particular with helping users gain proficiency in using the system. Projects Leaders also manage numerous projects within the site that further organize researchers by specific interests. Among the current projects are the 1776, Acadians, Australian Convicts and First Settlers, US Black Heritage, European Aristocrats, Puritan Great Migration, Scottish Clans, U.S. Civil War, and U.S. Presidents projects. Many of the projects maintain Google and Facebook groups to keep members informed of current happenings and topics for discussion. Some examples of projects on the site
