Thanks. I noticed the existence of the 'project', and 'free space', and wasn't clear abou tthe difference.
My other question was how far I can trust WikiTree to serve my pictures. Does WikiTree assume they will be the owners of my pictures, and the work of everybody here? Is there a chance that in the future WikiTree will get owners who want to mine the personal data of everybody for profit? I see much about the code of conduct of WikiTree contributors, but little about the place where all this common effort is hosted. I hope that WikiTree is like wikipedia, a real commons, with the corresponding legal statements about creative commons rights that guarantee these commons for the longer run.
