Sorry I inadvertently posted this in a resolved thread (Why the change? 4.0) so I thought I'd re-post to get a faster reply.
I'm confused, are you guys saying that once the login page is hidden that no one can even register? Most of my problems with bots is that they keep registering and making me go into users to delete them. Will this plugin stop this or should I be looking for some kind of email authentication plugin so that they don't even get to the user page?
