I stand corrected in that by "refresh" I meant with one click the Rootsweb WorldConnect allows you to replace an existing tree with a new gedcom and there is no need to delete the old tree. It's not too obvious but I go to Rootsweb.com> click on WorldConnect Project. On the right side of the screen it says "Also go here to update or correct your existing family tree." I click here which brings up you existing tree. I ignore the "Add New Tree" button but click on my listed family tree. This opens up a window with some options one of which is "replace tree with a new gedcom"
