Unfortunately this probably is not a good option:

(1) Most users don't like to receive emails from service providers; DriveHQ has tried not to send emails to our members whenever possible.

(2) To send activity reports on a daily basis means we have to log all the activities, which is hard as we have so many users and so many files. It will also create a huge amount of emails to be sent / day.

(3) It is hard to prepare the email contents; sometimes a user may only upload one file; sometimes he might upload 10000 files. Whether to include all changed file list in the email is hard to decide.

I would suggest you to try our automatic folder synchronization feature available in DriveHQ FileManager. FileManager can let you easily share and synchronize folders among multiple PCs and user accounts.
