I am Matthew Archer, sometimes known as zamBz (pronounced zam·bee·zee, or /zæm'bi:zi/), which is derived from the Zambezi river which flows through eastern Africa, probably most famous for the Victoria Falls which features along the river between Zambia and Zimbabwe.
The name was more-or-less chosen at random as a username for my Dota 2 account, and almost anyone who's encountered it has had trouble both reading and pronouncing it. Against my better judgement I have decided to base my online identity around it.
I also (probably more commonly) go by Fincap. That was the first name that the World of Warcraft "random name" button generated for my first character, a Dwarf Hunter (a dwarf who hunts, not a hunter of dwarves).
