This is just a gentle reminder for any new readers of the blog who haven’t seen the “rules” before –while we really do welcome comments – ones that add information, or even ones that say “Well done” (blog writers are human after all) - this blog does not engage in polemics. If that is what you want you will have to look elsewhere. Comments judged inappropriate for this blog will simply be removed. But that allows a lot of leeway for readers to still send in comments. In the past, some vital leads have been provided in this way, and we really do appreciate the interest shown and help offered by various ones.
