I posted a bug just now (Referenced topic isn't automatically shown in the Linked section on the ELL site?) and then I guess I encountered another one.
Usually, after someone else answered my question, the SE would send me a notification.
about 8 mins ago, a nice guy answered one of my questions on ELL ("sound natural" vs. "to be natural"). I haven't received that notation since.
On the other hand, I did receive other notifications, which are for some comments on the bugged question and another question.
