that new users often forget to link usernames
Not sure I follow this...
It would be nice to receive notification whenever the person who has asked the question comments on the question thread
The notifications FAQ mentions:
- The first author of the question or answer will always be notified of any new comment.
- If a user comments on their own post and there is only one person who has previously commented, then that person is also notified if
@name is forgotten.
- Notifications apply to the author, commenters, and editors of the question or answer that you are commenting on—users not in that list
cannot be notified
So if anyone has commented or edited on post - the person will be notified.
