Integrating forum with CI

[eluser]Computerzworld[/eluser]
Hello Friends,
I want to integrate forum with code igniter so that any user that is registered from website that is made in CI will be automatically registered to forum. And some other forum functionalities are also need to be modified. Which is the best compatible forum for CI? Please help me. Thanks in advance.

This is an excellent forum. fully developed by CI and output is looks like CI forum. moreover, when you have full control over the forum codes it's not a big deal to "registered from website that is made in CI will be automatically registered to forum"

You could also check my signature and find that we already built 3 forum bridge plugins (vB, phpBB and IPB)
