I am pleased to swap my research with distant rellies etc. but now state that no living people be put on the Net, ...... I naively also put my files on 'Gencircles' years back to find they were copied & claimed as that person's work, I mainly put them there to help other rellies & make contact, but withdrew them when they were talking of charging to look up information on other trees.
I've also noticed Ancestry seems to glean the information from these sites & some rellies don't like the LDS's practices, so it all becomes very complicated.
I only have my own ancestors on the Net now, I feel it's safer & easier to handle.
Cheers, Yvonne
