I gave up messing about trying to integrate vB in Ci and built my own forum system in CI. I've coded forums before by hand, but it's much quicker and easier in CI and there are no compromises - it works the way I want, has the features I want, isn't bloated with features I don't need, and it's light weight and efficient. My site uses
HTML5 Boilerplate and
Twitter Bootstrap (see
ci hb5 and bootstrap combi here) so my forums do too which means I don't have to waste any time on restyling and it looks and works great on mobile devices too. To be honest, although my forum isn't completely finished yet, it has taken less time to make than it took to integrate vB into the hand coded development of my site. In fact I actually spent more time searching the web for how to integrate vb with CI than I spent building my own forum system! So I'd recommend you have a go at building your own - you'll find it very rewarding! I used 1 x model, 3 x views and 1 x controller. My site uses
CKEditor and
HTMLPurifier library so my forum makes use of those too. My only issue now is that I have a vB license going spare.
