Spam removed

Posted by on August 2nd 2013

We do not want to prevent legitimate users from posting (and commenting on) articles on this site.  This is to be encouraged. But there has been a spate of spam in the last few days, which has now been removed.  Anybody who now joins the site will not be able to post unless their identity is verified using the contact form.   My apologies for any inconvenience caused by this change.
