Dear Dauoll,Absientely spot on yet again sir.JulesUKp.s. Can you explain why EVERY (and I mean EVERY) time I try to send a link to one of your articles on facebook, FB demands me to complete one of those "identify the obscured text" security checks before I can post it. Seems mighty strange and a tad sinister that your blog is being singled out for this treatment time and again?
