Hey Arie,
We're actually ditching phpBB (the current forum software) early 2017. phpBB is terrible in so many ways. We just never had the resources to ditch it completely (and alternative forum software paid & open source had their own problems -- many of them duplicating the problems of phpBB).
We've invested a lot of time making forum software that is fast, secure, responsive (meaning it looks good and is usable on mobile devices), and open source. We'll be rolling it out here first, and then releasing the source code with an announcement and all that jazz.
Long story short: we're aware of the many limitations of phpBB.
