I find it cumbersome to have to @mention someone every time I want them to know that I commented on a card (especially when there are only two of us on a board). I added the person as a "Member" to the card – but not sure if they are getting notifications without using @mention.
If the answer to the question is "no", then can someone recommend a more streamlined way of ensuring board members get notified of cards they are Members of?
Best Answer
Yes, members (and also "watchers") of a card get notified for comments, due date changes and card moves.
