 One useful feature of the OSF is the use of commenting. Commenting can be enabled on any OSF project. To leave a comment on a project that has been chat enabled, you click on the blue speech bubble in the corner of your screen. Then, simply add your comment to the box. The administrator can choose to allow comments from everyone or comments from contributors only. This distinction is found in settings in the gray navigation bar. Select the preference under Configure Commenting to control who can comment. This is a great way to get feedback and interact with the people who view your project.
