I have decided to put in BVE Developer Guidelines to my route,
in other words, copyright. (And at the same time, support it too.)
Link: http://www.railsimroutes.co.uk/developerguidelines/

Excerpts from the site:
"The supporters of the BVE Developer
Guidelines, including some of the most well known, valuable and
longest serving contributors to the Western BVE community, share
similar values and sentiments regarding how we would like people to
treat both ourselves and our work. We understand the real meaning
of Freeware,
and we may retain the rights to our work if we so choose, while
still enjoying good co-operation and sharing of ideas. We may give
away some of our work freely for others to use if we so wish, but
unless we've stated this clearly then we want to be asked before
our work is re-used."

This decision is FINAL. Joey, don't
bother changing. Even if you are a developer, I am still the
creator of this route. Infact, I'm the CEO.
Btw, if you think I'm kancheong, I'm not. This route contains
not just mine but other people's stuff, and I asked permission.
People who edit this route and release without permission, you may
get into big legal trouble or arguments (unless the stuff
is/are open source, then as long as you credited the original
author, then you are safe.)
* Waived as in, if you get permission from me, then the
conditions will be void.
