Clicking on the Chat icon on the Project View brings up the panel for the text chat window. This is a public text chat amongst all the active team members in this project.
Any Workspace User can type and send a simple message to everyone, which will be seen by everyone.
Workspace and Project Admins have the ability to download a log of the chat that happened on a specific day or a duration so they can review it based on the needs of the project.
This log includes timestamps that can be used for reference in a post production workflow.
