Which feature in Smartsheet helps in maintaining a history of discussions related to a project?

The feature that helps in maintaining a history of discussions related to a project is Comments. Comments in Smartsheet allow users to have threaded discussions directly within the context of a sheet or a specific row. This ensures that all conversations related to a particular project or task are easily accessible and can be reviewed at any time. By utilizing comments, team members can ask questions, provide updates, and collaborate in a streamlined manner, all while maintaining a clear record of what has been discussed.

Attachments serve a different purpose, as they provide files or documents relevant to the project but do not facilitate direct discussion. Notifications are useful for keeping team members informed about changes or updates but do not create a discussion history. WorkApps is a platform for building applications that integrate with Smartsheet but does not specifically cater to maintaining discussion histories. Thus, comments stand out as the dedicated tool for fostering communication and tracking conversations over the course of a project.
