To email me, you can use the box below or the email address above.  It is not necessary to tell me your name, as this website is about exchanging ideas - it is not a social website - but an identifier will be helpful so comments can be attributed.  This is a moderated discussion, so it remains tidy and the quality of discussion remains high.  On some sites, comments quickly become trivial, relate to other comments, go off-topic, and commenters even start slagging one another off.  Let's keep it civilised and constructive.
