Jeannette, my fellow ginger, I don't think we'll ever be able to find any curator who knows the details of every single village of their home country or region. If that became a requirement, we'd have no curators at all. Just the same, we can't know the details of every single family tree we work on, but we do our best with the information that is available. That's all anyone can ever do in genealogy.
If you find an error, please simply report it to the curator in question so that (s)he can fix it. I know you say you want curators to communicate more and better, but the same has to be expected of users as well. Communication works both ways, so please use your own courage -- which I know you have plenty of! :) --- and speak up to curators directly when you find an issue. We don't want to be in a situation where people are posting abstractly on the discussion boards about problems but not communicating the specifics directly to the curators in question. We need everyone's help in keeping things working well.
