Just suggestions to enhance an already wonderful site and application!
I am interested to see if a preservation policy is in place in terms of both the digital objects (photos etc.) as well as the data itself. It is my experience that digital preservation is not considered seriously enough. Wikitree is a collaborative effort and as an individual contributor, I have received numerous digitised photos and letters from family members. My concern is that although all of it is placed on wikitree, we cannot expect wikitree to preserve (and ensure access to e.g. JPEGs in 50 years), or can we?
Having this expressed explicitely would imply that each contributor would be required to ensure that all the time and effort digitising items are not wasted and that we ensure that the data and objects are part of a heritage.
In addition, I could not see any risk management policy (i.e. backup procedures and who is responsible for what (the end-user or wikitree staff).
Maybe I missed it?
