What happens re: subscribers if you start out with a public site and later decide to make it private?
I was under the impression that private blogs don’t send out subscription emails. The reason I mention this is because there have been occasions when someone in the forum wants to update an old post without a notification being sent out and some of us volunteers have suggested making the blog private, making the changes, and then making it public again. It seemed to work.
Sites that are private do not publish an RSS feed, do not have their Posts added to the global tag pages, nor do they appear in any search. Visitors arriving to your site will see a log-in page and unless you have invited them to view it, they will not have access. In order to be invited, visitors must have a WordPress.com account.
