> Have I really recieved this email a billion times?
No, only a dozen or so. I had this problem months ago and absent mindedly sent mail to extropians from the same account that seemed to cause duplicate postings before (it doesn't cause duplicate postings on any other list, so it must be some weird interaction with the extropians list software and/or MTA). I've contacted the list administrator about it.
