Hello,
Right now, moderation shows the "last updated by" for Q&A pairs added to the library as the individual who marked the project as complete. Netcall has requested that we display it in its place or next to it who marked the question as "save in answer library". This will help their content manager track down the reason for adding this Q&A pair to the library.
I've shown them some workarounds via project activities and project search filters, but this only works if they are proactive in researching before completing/archiving a project.
