I'm not an Ancestry subscriber at present and therefore did not volunteer as a Beta tester for Treeshare, but I'm wondering why the functionality is almost promoting the many database approach rather than making use of Named Groups?
If I was Sharing and collaborating with another researcher it would not be my complete database but rather those connected to a particular family or Surname but for me to achieve that I need to export that set of individuals our to a new file. I know Named Groups can easily change but I worry about endless duplication being produced by this process.
Should the creation of Sharing Groups not be catered for within a single RM database?
It has already been mentioned by others but should Lists > Fact Type List > Edit not allow the exclusion of certain facts from sharing with Ancestry?
