Several months ago I struggled with integrating a forum into Joomla with a bridge. I spent hours and hours and finally weeks trying to achieve a seamless integration but it never came out right and one thing or another was always wrong or didn't work the way it should have. In disgust, I gave up vowed to never bother integrating a forum again.
Then along came JFusion! It took me all of about an hour to install and make the integration functional, and the results are absolutely amazing! Perfect! And I didn't bang my head on my desk at all today while doing it. I can't say enough great things about JFusion and the folks behind it.
