Joomla! Discussion Forums

I already have Joomla installed on Godaddy hosting. I also have the Kuena forum installed on this website, but I want to also integrate phpbb 3.0. How can I bridge it with my current joomla install?

The most comprehensive bridge I have come across for this is JFusion, I can recommend it.

And what about the visual intrigation ?

I wan't it to look something like Joomla Forum,
or like http://www.phpbb.com/community/
