Please use Reply to All.  There are a lot of good reasons for this.
For me, personally, it's because often I simply don't have time to
look at my email.  On community forums, asking questions to the
communities is a matter of building programming language communities
and avoiding the burn-out of individual contributors.

But I do recommend that you at least read through the link I sent
earlier on "How to Design Worlds".  You're missing some terminology
and basic conceptual background, and you do need those in order to
solve the problem you're having.

In short: there are actual ideas in that book, some of which are
actually useful!  :P

Less flippantly: the book link's introduction should provide some of
the background that you are missing.

If you have questions, please feel free to ask the mailing list.
