No necessary when you explain it correctly for people you don't care
about its chemical make up they only have time to get the job done,
imagine if that's all people did was read manuals every day at company,
and there was manual for everything. They would never get anything done
period.
When your boss gives you a new task to do he doesn't walk and give you a
20 page manual and say "here read this before you do anything", he tells
you clearly how to do it so that you don't goof up. :)

Andrew, Split DNS is simple once you understand the concept. It is the
concept that most people such as yourself take a while to understand and
which necessitate screen shots and paragraphs of text to explain.
