Hi David
Clearly I am not up to speed on this issue, is there
anything on the web that you could point me to that
would allow me to increase my knowledge. (I had a look
at the W3C Semantics site but I can't get anything our
of it). Preferably short and 'low level'.

I am also lost when you say 'your mail program is
using MIME header encoding on your name when there
are no characters in that require it.'
I am using Yahoo Email, is what it is doing
inaccessible? If so, I would like to try and fix it.
