We obviously agree it's superior. Last month when we were racing to setup this extension site before CMS Expo, we threw Kunena up as we had used it before and, with the quick timeline, didn't want to play with something new (to us). Then, at CMS Expo we actually met the jVitals guys, loved our conversations and realized that we agree on a lot development and goals-wise. 2 days later, we migrated these forums to Agora!
In short, Agora support is coming to JFBConnect. I don't know the timeline exactly, as we announced that 2.6 would be the last feature release for the 2.x branch while we focus on 3.0 which integrates more, better features from FB's new API.
Keep checking back, and we'll note this as one user who wants Agora support. Thanks!
