In the messages area of a project, you can post a new message to the project by clicking the 'Add a Message' button in the top right.

You'll see a screen where you can add your message subject, content and choose:

  • who to notify by email
  • which category the message belongs to
  • who the message should be private to
  • any files you'd like to attach
  • to add a tag

When you click 'Post Message' it will be added to the messages area of the project, and notifications will be sent to anyone you selected in the notification options.
