Hi kids,
They're about to release a brand new version (v3, or "Olympus" -- currently we're on v2.0.22, if anyone cares!) of this forum software (see
http://www.phpbb.com).
It has heaps of new features, and when I upgrade to that some time in the next few months I'll enable private messaging, since there seems to be a demand for it.
Cheers,
Oliver
