<div class="bm bw0 pgs cl">

        <span {if $_G[setting][visitedforums]}id="visitedforumstmp" onmouseover="$('visitedforums').id = 'visitedforumstmp';this.id = 'visitedforums';showMenu({'ctrlid':this.id,'pos':'21'})"{/if} class="pgb y"><a href="forum.php">{lang return_index}</a></span>
        <!--{if !$_GET['archiveid'] && $_G['group']['allowpost']}--><a href="javascript:;" id="newspecialtmp" onmouseover="$('newspecial').id = 'newspecialtmp';this.id = 'newspecial';showMenu({'ctrlid':this.id})"{if !$_G['forum']['allowspecialonly'] && empty($_G['forum']['picstyle']) && !$_G['forum']['threadsorts']['required']} onclick="showWindow('newthread', 'forum.php?mod=post&action=newthread&fid=$_G[fid]')"{else} onclick="location.href='forum.php?mod=post&action=newthread&fid=$_G[fid]';return false;"{/if} title="{lang send_posts}"><img src="{IMGDIR}/pn_post.png" alt="{lang send_posts}" /></a><!--{/if}-->
        <!--{hook/forumdisplay_postbutton_bottom}-->
