Please be aware that the independent Worldwide One-Place Study Register, which most members of the WikiTree one place studies project will be aware of, and many had registered with, has closed. The decision was prompted by the new European Union General Data Protection Regulation which takes effect from 25 May 2018 and issues with third party service providers.
Now the good news .. the One Place Studies Directory has taken its place and captures no personal data - it simply directs interested parties to the appropriate WikiTree one place study free-space profiles where these exist. United States studies are the first to be transitioned across and other countries will follow shortly. Owners of one place studies worldwide with no current web presence will be encouraged to consider joining WikiTree and the one place studies project.
