No need to apologise
It was a valid thing to do. Conceivably, I should apologise to you for deleting an on-topic post! 8-)
I just wanted to make sure the posts didn't hang around too long. I checked on google and about half of this subthread was already indexed, but not the crucial post. Trouble with google is that once it's bitten-onto something it keeps a local cached copy so even if we delete the original message, the information is still out there...
(you might also consider asking Robert to pass-on email addresses to the other party)
