My b2evolution Version: Not Entered

I have been playing around with b2evo for a few weeks now, trying to get it just right before I actually go live on it's own domain name. However, I need to either remove altogether or just move it to a more inconspicious place, the login link. The site and blogs are for a specific group of people. I don't really want everybody in the world to see the link and think that they deserve a username here as well. Also, as the skins on the various blogs change often, I really don't want to edit each and every skin.
