Notes

This operation should really be a function for the administrative functions of the Investigator Toolkit. It is reasonable to expect that (especially for the first iteration of the infrastructure) MN administrators will want to peruse and evaluate the log data. In later stages, this information could be associated with content, so use statistics appear with search results.
