There is a new rule for Sprinters and Sourcerers regarding the Hold Requests used by Projects for their learning programs. Profiles with a Hold Request Research Note box should not be improved as part of the Sourcerers Challenges/Saturday Sprints. These profiles are reserved for use by the named Project to help members learn the ins and outs of using WikiTree. You can find more information on the Hold Requests Help page. To learn more about the various Trails, the Voyage, and the PATH, see the Projects' list of opportunities.
