[support] Login

Hi, Login is necessary for admin to control the contents or for editing the website. But i don't want login option for anyone just an info webstie. So in that case is it possible to just disable login for other user apart from admin. I'm confused that if i disable login using admin won't next time i admin will also not be able to edit the website.?? Thanks. -- Chetan Arvind Patil, +919970018364
