If you want to be regularly updated with a specific report you can set up scheduled report.
To schedule a report, select a report type then click the 'Schedule report' button (this can be done from the usage reports section pre version 3.1543 and from both the usage reports and audit reports sections post version 3.1543).
You will then be asked to specify a name for the report and how frequently you want it to be generated (daily, weekly or monthly). By default, scheduled reports are sent to all admin users as an email attachment at the frequency you have defined. You can also specify other groups of users to receive the reports using the 'Additional groups' checkboxes.
You can view what scheduled reports you have set up at any time by clicking on the Scheduled Reports tab. From here you have the option to delete any of your scheduled reports.
