Guess I could test this on a live system but what happens if you post a topic and then edit it to include some more @usernames? Does the system send the notifications just to the new username added?
What notification, and to whom? The “author” of the post should get an edit notification, but that’s it.
Misread the question, please see new response below.
The email notification that your name has been used in a tag like @jomaxro when you’re on normal watching status
The answer to your question is yes.
If you (or a moderator) edit your post later to add more @ mentions, those people (or groups) will indeed be notified (assuming they have access to the post).
This is a common question in our community. We use it all the time.
Ah, I misread the question, sorry! I saw “tags” and missed the “@”. Yes, edits that add “mentions” will cause notifications - sorry for any confusion I may have caused.
