I'm using moodle 2.5 and have to familiar with it. Is there a simple way that I can temporary make the site un-loginable (say between 11pm and 6am or at the weekends) for me (admin login) to do some site and course maintenance? Ideally, any attempt from users who try to login will pop up a simple message of notification. Appreciate any advices. Cheers James
Yes, place the system in maintenance mode.
