Hello!

This "problem" should be an easy fix! The solution is right in front of you!

Below this box Im currently typing in there is a checkbox that says "Receive notification email when a new comment is posted on this idea (you can unsubscribe at any point)"

That is exactly what I want on cards. It can be checked by default so those who dont care about this change dont get affected.

If you create a card or comment a card, you get notifications for every new comment on that card.

Example:
If I created a card and wanna ask a collegue about something related to a card I type @[his/her-name] so that collegue get a notification. Thats fine, my colleague answers and everyone is happy.

The next day I got another question to another colleague and type @[his/her-name] so that colleague get a notification.

But now, both my collegues got notifications and the first colleagues go nothing to do with this question.

The day after I make a comment as a note on that card. A note thats meaningless for my two colleagues. But since they once where mention by @, they get notifications.

The solution:
The solution for this is a checkbox that says "Subscribe to card".
If you create a card this should be checked by default. If you uncheck it you should only get notifications when someone is asking @[your name].
If someone notified me I can then chose to check it if I want to get notifications for the following comments regardless if it's for me or someone else.

I have created 300 cards in a project that I dont want to get notifications for and when assigned people start working with these cars, I will miss the notifications that really matters.

Best regards
