Ability to report on number of reviews against a list during a specific time period
To run a report of all lists which generates the number of reviews carried out on the list. Ability to refine this report to specific time frames.
The All Reviews report allows you to download reviews data that contains each review that has been completed on a list. Using the download you can filter by time period and then list title to get a figure for how many times a list has been reviewed in a given time. This should meet the requirements of this idea but please do raise a new idea or a support ticket if you would like to discuss in more detail.
