I have been contacted by a couple of users who have received unsolicited, commercial email. The message was metrology related which gives rise to the suspicion the email addresses may have been lifted off the forum.
If you receive any suspect email please forward it to me (with complete headers intact).
I will intervene if it is clear the UCE is targeted at forum users.

Sincerely,
Duncan Mackenzie
