Thanks for your response.
I did try that but it relies on time input. Where as the "View Member's Board Activity" already has the activity if not the actual hours.
Not sure I can get the actual hours logged but it is still important to see what has been actioned and what else needs to be in a month across 5 or 6 boards
I am also a bit late here. But we had the same requirements at UBit and implemented an in house solution, that we are now sharing with the community. It allows filtering card activities based on members, boards and actions. It is possible to specify a time window (e.g. last month). This has increased our productivity, because we are able to find loose ends easily. Feel free to download the trial. Good feedback and ideas will be rewarded with a free licence:
