To manage your reports you need to go to the "Reports" section of your settings. Hit the "create report" button. You will find here a form to fill in:
- name of the report
- project from which you want to send the report
- which dashboard you want to report on
- the time period from which the report is taken (last week, last month, etc.)
- the frequency which reports are sent
- if it is a regular report, you must also choose the email address that it will be sent to
Finally, just click "Save" and your report will be set.
You will find a list of reports in "Reports history" (which is located on the same page) including one-off and regular reports.
