If you want to keep it simple and your userlist is set to only be seen by logged in users, then edit header.tpl:

find:
Code
{if $user_list}
<a href="{ubb url="ubb=showmembers"}">{$lang.USER_LIST}</a> 
&nbsp;&nbsp;&nbsp;
{/if}
change to:
Code
{if $user_list}
<a href="{ubb url="ubb=showmembers"}">{$lang.USER_LIST}</a> 
&nbsp;&nbsp;&nbsp;
<a href="/mynewpage.html">My New Page</a> 
&nbsp;&nbsp;&nbsp;
{/if}
