I do not use on-line trees; all my work is in FTM on the computer. I do use web search (leafs) and merge material into the computer file.
I just received the 'go' on my ancestry DNA, have been charged, and it is shipped (oh, you cannot get it for $99...another story). But I also found out that to get any of the "connection" output from the DNA test, you HAVE TO HAVE an online tree.
So, now my question is, can I upload my tree but have ONLY changes I make locally sync. In other words, I don't ever want any changes to the online tree to sync back down (in case a glitch fouls up things--as we have seen happen in the past).
