It's supposedly pretty new.
the problem with the version of phpbb we have now is the inherent glitches due to a lack of continuous updating due to my being an idiot when it comes to updating procedure. we got so far behind that when I finally asked our hosts to do the update for us, there wasn't a patch that brought our old version up to date. So the closest one was used. Didn't turn out all that well. And subsequent updates have only made things worse and we had to backtrack to the frankenstein you see now. If we get the most up-to-date version, it'll be just like a conversion to another software; i.e. only threads and names would transfer (without a ton of work).
The big selling point for the fusion is that the people at our host company are very familiar with it. right now, no one I know is uber familiar with phpbb. Well, probably not no one, but I pretty much have to hand the keys over to whomever would be doing the work, and I tend to hesitate doing that. If I could find someone local to me that could simply show me how to do all of it, that would be ideal. but I haven't found that person yet. :dunno:
