I don't know english very well but I want to give my opinion.

JFusion is the best extension I have tested, the support team is very good and the members are very friendly.

At the beginning I had problem with the configuration of some options but I reading the documentation and help of the members support forum I have been able to configure perfectly JFusion in my website.

I use the following plugins and options:
- JFusion Login
- JFusion Search
- JFusion Discussion Bot
- JFusion Activity
- JFusion Bridge Joomla PhpBB3
- JFusion Frameless Integration

Everything works great!
