I'd read the shit out of those books.

Sorry if this is off-topic, but do you "become" a mekboy, or are you born one?

IIRC, the Mekboy genes are programmed in some Orks.
That said, I think that its possible that an Orks has the programs to become different classes in-lore.

I would love it if there were some more oddboy characters. An oddboy nob would be hilarious.

Oddboys get born when the Ork-society needs them: The communal psychic field of the Orks takes care of that.

You are a Mekboy from birth onwards, but IIRC the genetic knowledge awakes not immediately but after a while.

I'm going to try TRY writing a book about an ork yeller (priest) thats about an orks view of the other races and their faiths he travels the universe gaining trophy's and momentos like a snake of khorne and a staff of nurgle

I would love a book from the Ork point of view. Been reading the beast arises series but it doesn't have nearly enough ork in it

I reckon a Painboy and a Mekboy have got to be fairly interchangeable?

Same tools (hammers, saws, screwdrivers), same process (more dakka, more bitz), just a different subject.
