Hey, you might recognize me from Warseer.
I'm Matt, I live in Boston, Massachusetts, but I'm from the UK. Last year some friends and I formed BosKOW, the Boston Kings of War players group.
I collect Dwarfs, but I've started picking up various other armies so I can do more demos. Right now I've run a few demo days for Mantic in the North East, and last year I wound up on a small speaking tour and took along a box of Dwarfs to play demos of Kings of War with people along the way.
I also collect old-school GW stuff, but don't play any modern games other than the occasional game of Blood Bowl, and I guess even that can't be considered modern now, really.
One cool thing I did I'm proud of is write and produce a short film about the free software movement and GNU/Linux. The movie stars Stephen Fry and was released in September 2008. You can watch it here --
