Hi, I had private conversation with Andrzej Jaworski about the fact that his reply to Alberto Ruiz's post is off thread. What he did was clicking on the "mailto" link beside the author's name on the list archive web page [1]. [1] http://www.haskell.org/pipermail/haskell-cafe/2008-June/044023.html I am not quite sure about what this link is supposed to do. But, if it is meant for people to click and reply to the thread, it is not doing this correctly, as the "Subject" and "In-Reply-To" fields in the link are obtained from these fields in the head of current email. It would be useful if the link shows "Subject" with an added "Re: " if there is not already one, and fill in the "in-Reply-To" field with the value from the "Message-Id" field of current email head. An optional "Reference" field is informative for most of the email client, too. Sorry if this topic has the least connection to the glorious Haskell. Best, Xiao-Yong -- c/* __o/* <\ * (__ */\ <
