Grovelling apologies: this string from about 2 months ago was “spammed” about half an hour ago by an intruder trying to advertise a commercial paper writing service. I happened to be online and saw the intrusion, so I attempted to mark the single offending post as spam, but the result seems to have been to delete the entire string.
We answered the original enquiry at the time, and I hope that the member concerned has long since picked up the response. But if anyone still needs answers to this question please post again.
