Blackson is a fairly well known member in the Metanet community. He is a moderator on NUMA and a moderator of the N Map Packs forum.
Recently Blackson hosted a Quadradius Tournament over Summer 2009[1], but it was ground to a halt by the lack of participation by some of the vacationing participants and his own wonky methods of running the thing. He has recently started up a second Quadradius tournament.[2]
He is internet famous for discovering a pulsar (a spinning neutron star; basically what remains after a star slightly larger than our own Sun runs out of fuel and explodes).
