XF 1.5 Adding a Newest Members tab to Notable Members Tab

[falsecaterpillar]

Hello, I was wondering if there was a way to add a tab to the Notable Members section with a list of the forums Newest Members? I imagine it would take altering this:

<li class="{xen:if '{$type} == "messages"', active}"><a href="{xen:link members}">{xen:phrase most_messages}</a></li>
<li class="{xen:if '{$type} == "likes"', active}"><a href="{xen:link members, '', 'type=likes'}">{xen:phrase most_likes}</a></li>
<li class="{xen:if '{$type} == "points"', active}"><a href="{xen:link members, '', 'type=points'}">{xen:phrase most_points}</a></li>

To include an option for the newest member, and possibly updating the member.php file, but going about this is a little over my head.

Thank you!
