三.注意事项：

该插件需要在评论的form表单中加入以下代码来控制邮件是否发送

<span>
<input name="receiveMail" type="checkbox" value="yes" checked />
<label for="receiveMail"><strong>接收</strong>邮件通知</label>
</span>

如果模板没有相关设计可参考下列代码修改Plugin.php 272行

$r = 1;
// 当前评论是否接受回复提醒
/*
if (isset($_POST['receiveMail']) && 'yes' == $_POST['receiveMail']) {
$r = 1;
}
*/
