Just want to tell what happened with me.
I was looking for a suitable CMS to be used with my website since a long time and finally picked Joomla.
I needed a forum and I didn't found anything better than phpBB3.
I need a dual login for the whole website including Joomla and phpBB3.
I've tried some bridges for some individuals and did not found anything suitable.
Later on I've tried the Rocket Werx Bridge as the rocket theme team released amazing styles for both of phpBB3 and Joomla and the bridge worked fine with phpBB 3.0.2 and when I've updated to 3.0.3 & 3.0.4 later on I had some issues that has not been solved yet, but this is not our topic now.
I've tried JFusion 3 days ago and I have to mention something regarding this bridge:
1- Really piece of cake to install and set.
2- Working like a dream.
3- When I had an issue I've found one of the team members replying me with an amazing support and solved all the issues I had.
The bottom line is that I am glad using this bridge and I hope to find it like that all the time especially when updating any of Joomla or phpBB3.
