When you are giving feedback on a post, or leaving a quick remark, you may need to call a fellow team member into the conversation.
You can do this by typing the user’s @username in your comment…
… or by starting with @username and then choosing from the suggested contacts.
Keep in mind that you can only @mention users that are Members of the Place you are trying to @mention them in. If you @mention a user that is not currently a Member of the Place, you can:
if you are the Manager of the Place, or if you are, as a Member, given the permission by the Manager to do so.
