This may be entirely impossible, but I've been wanting to shore up the security of a Wordpress CMS for a family friend. Obviously, anyone who goes to http://site.com/wp-admin will see a login screen, which MAY be susceptible to potential hacking. What I'd like to do is the following.
Outlaw direct access to http://site.com/wp-admin...if someone tries it, they get a "Page not found" or similar message. Then, a secret link http://site.com/loginscreen would automatically re-direct to wp-admin and it would work.
