Azure, in comparing your message to Chris' message and the Ambassador Project page, your message does not include mention this part of the project: liaise between WikiTree and genealogical societies, libraries and historical groups.
Is there a group/project focused on this? I am not very active in forums, social media, or blogging, but would be interested in approaching organizations to link to WikiTree pages relevant to their collections and also asking for any genealogical research they have done or working with volunteers to update profiles and possibly create free-space pages.
I have been thinking about who I'd like to approach first and am happy to continue on my own, but if there is an existing group or common interest, I'd love to exchange ideas and learn from the experience of others.
