The original idea behind the BNS-Login plugin was from editing themes for use with a WordPress MU (WPMU) installation I had set up. It seemed I kept choosing themes from Extend that did not have a satisfactory link to log into, or access, the dashboard of the blog. It may have been more a personal preference than anything else but the idea has been in the back of my mind since then.

Version 1.1 of the BNS-Login plugin now offers WPMU compatibility in the form of redirecting the log out URL to the main domain (home page) of the WordPress MU installation.
