For those of us who don't get this publication and are discouraged to ask for any letters (completely against John from Arrans own guidelines - a bit like allowing yourself a cigarette with a pint if you are in Parliament)
maybe take a leaf from Big Daves site
http://bigdave44.com/
and use transparent writing.
ie
Typing
<p>{<font color=transparent>ans?e?</font>}</p>
will result in
{ans?e?}
The p just means open a new paragraph and the brackets are to indicate where to highlight.
