Dropbox Features

Would you know if Dropbox is capable of controlling any attempted changes in a document...or would send a report stating any revision request from the users? If you're not a dropbox user, would you mind sharing with me the cloud storage service you're using? Thanks.

Hi. In Dropbox, all changes made to the shared folder are synced to anyone else who joined the folder. Everyone given access can edit the file anytime. I hope this helps.
