Jill, How things change.
Remember this? -
http://www.rootschat.com/forum/index.php?topic=787945.0Questions - Still undecided about creating a tree on Ancestry following DNA test
I presume that question has been answered by yourself!
Just as a quick add on -
My tree was initially private, changed it to public shortly after getting my DNA results back, as I realised how problematic it was when close matches had private trees.
I still would have preferred to have my main tree private, so recently uploaded a smaller gedcom, originally from ancestry, so exactly the same names, places and events.
All my DNA matches can see it, but it does not, as far as I can see, turn up in searches. This is because I have added no additional Ancestry records to this new tree as someone mentioned that it would not then come up in searches.
If anybody clicks on my Ancestry profile, they would be able to find out that I have a tree and access it, but not many people will do that.
So best of both worlds, a large private tree and a smaller public tree with limited access. And I do respond to any messages from DNA contacts, though mostly it is me sending the messages.
