Further to this, I've found that the software package is indeed free, is under a GNU license agreement, and I note that there is a language pack available for it too; don't know how you'd utilise it, but it's there.
The link:
http://www.phpbb.com/downloads/I note too that the site offers suggestions, with prices, where such a forum might be hosted, I think they are all USA located, haven't checked thoroughly.
Those more conversant with these technologies might be able to advise further.
Oh! As an additional thought, the GNU license does allow software modifications to be made so that with the right technical advice, if Aceboard does use this technology, Shark with direct access to the software can bring about changes at his calling and not a provider!!
This is also worth a read:
