Good morning Andrew,
Thank you for responding to my question. Regarding the "pruning" I only see a week's worth of activity under the audit trail. That is why I made the assumption that there is a 1-week limit to the amount of activity described. However, in "researching [read: "fishing around"] I went into the User Log for the client and was able to find an audit trail of activity that met my needs for the question I had. [In other words, I got lucky :-) ].
Again, Thank you for responding.
Mike
