Were we adding too much to the FamilySearch "Family Tree?"
The simple answer to your question would be "no". Indeed, FamilySearch invites more and more people around the world to "add" good and genuine genealogical information to its databases. Steps are being taken to bring into service a vastly more effective database service, which will enable the capacity of FamilySearch to be increased manyfold.
So, please be successful by adding your good genealogical information, which is most welcome.
