Team members can quickly leave feedback for the entire team by posting comments. Suggestions are more private. (Think of dropping a suggestion in the suggestion box.) Suggestions can only be seen by the Producer who created the Project and any Co-Producers, but not Project Members. If the Project is a Client Project (as opposed to a Discussion Project), then the Consumer will also be able to see the suggestion.
Use Project Chat to share messages, files and to-do's with other project participants. Here, you can send direct messages to specific individuals, private groups of individuals you create, or the entire project team. Each Project has its own separate chat room so that messages from one project are never sent to the wrong project group.
