The art of the letter to the Editor:

Capture, Hold, Insight, and Conclude.
Write what you like,
But capture as a first!

This involves any of:
a) timing and issue!
b) captivating introduction.
c) maybe known identity, as author,
d) God knows as no law is 100%.

In New Zealand the standard is 200 words.
Be accurate, more than 200 words kills a lot of good letters.
Editors are ( have to be ) ruthless!

Cheers, keep writing.

Note: 80 words!
