Excellent, it worked and removed the last poster's name from the postlist.php index. But this neat little update wasn't included in the .zip file that I originally downloaded.
One other thing... a minor issue. While the last poster's name is removed by the update you provided, the timestamp of the last message (which was just deleted) remains in the index (in place of the original or previous date and time).
It isn't that big of a deal and most people probably won't notice it anyway.
Thanks much!
