We know working with multiple people can be difficult. With conversations scattered across email threads and chat windows, feedback can get lost and it can take forever to get everyone on the same page.
That process just got much simpler. Now you can post comments to files on the Dropbox website — so conversations stay organized in one place, and you can gather feedback in just one step.

To bring someone into the loop, just type “@” followed by their name or email address. They’ll get an email notification with both your comment and a link to go right to the file.
To try it out, go to Dropbox.com, click on one of your files, and add a comment on the right. To learn more about this feature, visit our help center.
