继续讨论来自 [全局通知，我在哪里可以找到它](https://meta.discourse.org/t/global-notice-where-do-i-find-that/107298) 的话题：

在阅读论坛时，我发现了上面链接的主题。这让我很好奇……“紧急、应急消息”有哪些具体使用场景？访客会看到什么样子？

由于这是我第一次听说这个功能，我想我只是希望总体上能了解更多相关信息。

Some use cases I can think of:

- Upcoming site upgrade with downtime - the notice gives users the time/date of the upgrade, and to expect downtime.
- Upcoming site migration with downtime - same as above.
- New site info - important information you need all users to know.

You can see a real-life example of a global notice at [Soaps.com's Message Board - Soap opera message board](https://soaps.sheknows.com/message-boards/). While that’s a heavily themed discourse site, it should give you an idea. It’s a simple message that appears at the top of all pages. For a non-themed example, see [https://try.discourse.org/](https://try.discourse.org/). Note, try resets daily so the notice will not be there tomorrow.

It appears to not be dismissable, unlike banner topics…

Thank you for the examples, Joshua. This will help as I become more experienced in working with the admin side of discourse.
