[建议] 公共消息提醒

七叔公

I find it annoying when the public notice that I have read so many times keeps reminding whenever I sign in.

In my opinion, public notice that has been read should be automatically removed from the list of notices. It'd be much better if we have an option to mark the notice as read.

我建议系统自动把阅读过的公共消息从提醒中删除！
