White border missing on #forum td.last-reply

#forum td.replies and #forum td.created have the "border:solid white 1px" style. However, the "last-reply" class didn't have it. So, I added that to the CSS of "advanced_forum.css" to make it show up. However, that same style is used in the template file "forum-list.tpl.php" on line 52. So, this adds a white border to a screen that doesn't have other white borders. So, I changed the 'class' => 'last-reply' to be 'class' => 'last-post' since that is the name of the column.
