Hi,
Yes, we had the discussion about what variety of Engish to use a while
back. The consensus at the time was US spelling and terminology.
IMHO, one of the biggest aids to comprehensibility is careful and
thoughtful punctation.
But I also try not to be lazy in my English and to be careful about
relative pronouns [1] and subordinating conjunctions [2].
One good idea, as suggested by Barbara or Hal, is to build-up a
separate and brief glossary of terminology explaining our conventions.
It could be useful to end users but it would especially be an aid for
translators.
As I mentioned previously, "activate" and "deactivate" are terms I use
a lot, but I do tend to vary my vocabulary so that the style isn't too
stilted and wooden. I generally attribute two ha'porth of common sense
to the reader.
My 2 cents...
