Limble allows for comments to be added to tasks. Comments are a great way to communicate with others about a task. When a comment is left on a task, other people involved with the task will receive a push notification and/or email. If an email is received, an email reply can be made and a comment will be left on the task.
How to add a comment
When viewing a task, select the "Comment" button.
View who will be notified
Select the text titled "Who will be sent notifications?" A list of everyone who will receive notifications will then be displayed on the screen.
Add someone else to be notified by the comment
From the current screen, it is possible to add other people to be notified. Select the button titled "Add Someone."
From there you will be able to select a Limble user or enter an email address.
