Yes, I know about it.

What I mean is that this kind of link: _http://www.example.com/forum/forum_name/topic_name/ is a little bit better for seo en much more beautiful than this one: _http://www.example.com/forum/topic/topic_name

And therefore this: _http://www.example.com/forum/forum_name/ instead of that: _http://www.example.com/forum/forum/forum_name

But my priority is to get faster indexed in Google so I do not worry much about it.
