Greetings: FORM/SORM (First/Second Order Reliability Methods) are very popular among some structural engineers but almost never discussed among statisticians. I am quite predudiced as to the reasons for this, but would enquire among the world's statistical thinkers for their perspectives on these methods. Any comments, pro or con, would be greatly appreciated. Since this is off-topic, you may wish to reply directly to me and I will summarize the comments to the group. Thank you. Charles Annis, P.E.
