Hello,
I'm attempting to rename (and hopefully add to) the tabs in the header: Published News, Upcoming News, Submit a new story in yget. I've checked out header.tpl and found the following:

{if $pagename eq "upcoming"}
		    <li><a href="{$my_base_url}{$my_pligg_base}" class="navbut3"><span>{#PLIGG_Visual_Published_News#}</span></a></li>
		    <li><a href="{$URL_upcoming}" class="navbut4"><span>{#PLIGG_Visual_Pligg_Queued#}</span></a></li>
		    <li><a href="{$URL_submit}" class="navbut3"><span>{#PLIGG_Visual_Submit_A_New_Story#}</span></a></li>
		{elseif $pagename eq "published"}
		    <li><a href="{$my_base_url}{$my_pligg_base}" class="navbut4"><span>{#PLIGG_Visual_Published_News#}</span></a></li>
		    <li><a href="{$URL_upcoming}" class="navbut3"><span>{#PLIGG_Visual_Pligg_Queued#}</span></a></li>
		    <li><a href="{$URL_submit}" class="navbut3"><span>{#PLIGG_Visual_Submit_A_New_Story#}</span></a></li>
		{elseif $pagename eq "submit"}
		    <li><a href="{$my_base_url}{$my_pligg_base}" class="navbut3"><span>{#PLIGG_Visual_Published_News#}</span></a></li>
		    <li><a href="{$URL_upcoming}" class="navbut3"><span>{#PLIGG_Visual_Pligg_Queued#}</span></a></li>
		    <li><a href="{$URL_submit}" class="navbut4"><span>{#PLIGG_Visual_Submit_A_New_Story#}</span></a></li>
		{else}
	    	<li><a href="{$my_base_url}{$my_pligg_base}" class="navbut3"><span>{#PLIGG_Visual_Published_News#}</span></a></li>
		    <li><a href="{$URL_upcoming}" class="navbut3"><span>{#PLIGG_Visual_Pligg_Queued#}</span></a></li>
		    <li><a href="{$URL_submit}" class="navbut3"><span>{#PLIGG_Visual_Submit_A_New_Story#}</span></a></li>   
		{/if}

But I can't find out where the PLIGG_Visual_X includes are! I've searched through at least a dozen different files, so any help would be greatly appreciated!
