Here's a quick paste in update.

For the "Build Form and Link" Plugin:

if($vbulletin->options['enable_mark_unread'])
{
	$template_hook['showthread_after_activeusers'] .= '
		<form name="unmark">
			<input type="hidden" name="do" value="unmark" />
			<input type="hidden" name="threadid" value="' . $threadinfo['threadid'] . '" />
			<input type="hidden" name="forumid" value="' . $foruminfo['forumid'] . '" />
			<input type="hidden" name="userid" value="' . $vbulletin->userinfo['userid'] . '" />
			<input type="hidden" name="s" value="' . $session['sessionhash'] . '" />
			<input type="hidden" name="securitytoken" value="' . $vbulletin->userinfo['securitytoken'] . '" />
		</form>
		<script>
			function vB_AJAX_Mark_Unread(form) {
				this.form = form;
				this.lastPost = ' . $threadinfo['lastpost'] . ';
				this.cutOff   = ' . TIMENOW - ($vbulletin->options['markinglimit'] * 86400) . ';
			}
			vB_AJAX_Mark_Unread.prototype.addLink = function() {
				if(this.lastPost > this.cutOff) {
					var unmark = document.createElement("li");
					unmark.innerHTML = \'<a id="mark_unread"  href="javascript:markUnread.unmark();">' . $vbphrase['mark_unread'] . '</a>\';
					fetch_object("threadtools").getElementsByTagName("ul")[0].appendChild(unmark);
				}
			}
			vB_AJAX_Mark_Unread.prototype.unmark = function() {
				YAHOO.util.Connect.setForm(this.form);
				YAHOO.util.Connect.asyncRequest("POST","showthread.php?do=unmark",{success:this.confirm,failure:this.confirm,timeout:vB_Default_Timeout,scope:this});
			}
			vB_AJAX_Mark_Unread.prototype.confirm = function(doc) {
				fetch_object("mark_unread").parentNode.innerHTML = \'<a style="background:rgb(200,50,20);color:white;">' . $vbphrase['marked_unread'] .'</a>\';
			}
			markUnread = new vB_AJAX_Mark_Unread(document.forms.unmark);
			window.onload = function() {
				markUnread.addLink();
			}
		</script>
	';
}

For the "Delete Query" plugin:

if($vbulletin->options['enable_mark_unread'])
{
	if($_REQUEST['do'] == 'unmark')
	{

		$vbulletin->input->clean_array_gpc('r', array(
			'threadid' 	=> TYPE_STR,
			'forumid' 	=> TYPE_STR,
			'userid' 	=> TYPE_STR
		));
		
		$threadid = intval($vbulletin->GPC['threadid']);
		$forumid  = intval($vbulletin->GPC['forumid']);
		$userid   = intval($vbulletin->GPC['userid']);
		
		if ($vbulletin->options['threadmarking'])
		{
			
			$vbulletin->db->query_write("
				DELETE FROM " . TABLE_PREFIX . "threadread
				WHERE threadid = $threadid 
				AND   userid   = $userid;
			");
			
			$vbulletin->db->query_write("
				DELETE FROM " . TABLE_PREFIX . "forumread
				WHERE forumid  = $forumid 
				AND   userid   = $userid;	
			");
		
			die('done');
		}
		else
		{
			set_bbarray_cookie('thread_lastview', $threadid, 0);
		}
	}
}

Not working correctly. It now fails to show the Mark Unread option in threads that are well within the timeframe (using database marking).

Fortunately, I didn't overwrite my saved copy of the previous version which was better, IMO.
