Dart will send all project notifications to your Dart Inbox. You can find your Inbox on the left side of your screen, just below My tasks:
Hover over each individual notification to reveal a "Mark as read" button (to remove it from your inbox). You can click on the task to open it and make adjustments right from the inbox. Once you've looked at a task, you can clear it from your inbox by hovering over it once more:
You can also choose the "Mark as unread" button on the top right, beside the setting icon, to show all inbox contents as "read."
Changing Notification Settings
If you need to adjust your notification settings, go to the settings icon at the top right of your inbox:
Dart has a default setting to help ensure you're getting important updates without getting spammed with information, but if you want to make your own adjustments, simply click the Recommended settings toggle:
Once Recommended settings have been turned off, an entire menu of options will appear:
Note that Dart allows you to get notifications right in Dart, or to choose to also have them sent to your email or Slack. You can even arrange it so that specific task notifications are sent to different places. For example, you can decide to send status changes to your email and assignee changes to Slack, or choose to have certain notifications sent to all three (or none at all).
