Hi everyone 
Is there an easy/quick way to shut down the forum or stop posting for a certain period of time? Other than changing all categories settings.
Any help would be much appreciated!
Well, the easiest way is to setup your forum in read-only mode. This means that the site remains online and users can only read topics but can not interact (reply, open new topics, put Like etc).
Thanks Daniela can you tell me how to do that?
Nevermind! looked it up and found out.
Go to your https://your-site/admin/backups page and click the Enable read-only mode
You can also configure a global alert that tells users that the site is paused, so they stay quiet 
하지만 (방금 메타에서 비슷한 게시물을 검색하면서 알게 되었지만) 이 ‘읽기 전용’ 모드를 활성화한 후 실험이나 작업을 하다가 (시크릿) 브라우저 탭을 닫거나, 어떤 이유로든 1분이라도 로그아웃하게 되면, 다시 로그인할 수 있는 방법이 전혀 없다는 점을 크고 굵은 글씨로 경고합니다!!
네, rails 콘솔을 통해 가능합니다:
Discourse.disable_readonly_mode(Discourse::USER_READONLY_MODE_KEY)
