How can a Tree grow and flourish without documentation? On my Fleckenstein Family, there are many names without any sources and some with odd sources such as http://home.t-online.de/home/j.fleckenstein/FL160_e.htm and World Family Tree, vol. 4, chart2417;;;; 17 Jan 1998 under Collaboration. Does anyone check these things?
Also, when Family Search adds infomation, why don't you attach the source ?
