(Note: _anyone_ can write and publish material that can be used with Your
Favorite Version of Traveller - that is, after all, _exactly_ what
Freelance Traveller is all about. An Author, with a capital A in The Rant,
is someone who is doing so _for money from an official licensee_. Even
I have, occasionally, wondered about the boundaries of this vis a vis publishing with TAS. I would do (I do do) my utmost to keep in line with what's gone before. Not to be honest, that I really push the boundaries.
But no one appears to police anything I publish as a "TAS" thing and I'm not sure they would as I don't imagine anything I write - let's say the details for the planet Spume in Ashfall - becomes any form of canon. Although as I understand the licencing, anyone can take what I've done and use it in their own Traveller publications under the TAS licence.
I would be chuffed if they did. (Whether a March Harrier thing or a Freelance Traveller thing). I'm not aware of anything that has so far done this but nor would I be surprised or put out if someone wrote, for example, their own entirely different version of, for example, Spume.
So perhaps there's something between an author and an Author. We need a third case!
though I've written rule material (for example, the Tavrchedl' career) and
background material (for example, the Kurishdam on Talk Opera), I'm not an
Author, and my stuff, even if it doesn't explicitly contradict anything in
Canon, is not itself part of the Canon. You want to incorporate it into
your game? Feel free; that's what it's there for. But it's still not
Canon.)
