allowing custom URL schemes just like Google SEO

[ATofighi]

   if($mybb->settings['tags_seo'])
    {
        define('TAG_URL', "tag-{name}.html");
        define('TAG_URL_PAGE', "tag.html");
    }
    else
    {
        define('TAG_URL', "tag.php?name={name}");
        define('TAG_URL_PAGE', "tag.php");
    } 

Why not allowing custom URL schemes just like Google SEO does it? Unless I edit your code I can't use "etiqueta-{name}" or another.

Instead of an yes/no option use two a text box setting.
