What’s this? Have we been teleported back to the late 1980s? :-) Could I remind everyone to use meaningful and relevant Subject: headers when posting to the mailing list. In particular, *PLEASE* do not reply to message digests. It’s inconsiderate and unhelpful to reply to message digests. So don’t do that. Thanks. Replies to message digests create unnecessary and easily avoided problems. Here are the main ones: [1] It messes up the article threading used by everybody’s mail clients. [2] It’s not clear which message(s) in the digest are being replied to. [3] The list archives contain completely useless Subject: headers (like "iot-wg Digest, Vol X, Issue Y”) which make it difficult when browsing the archives to find out who said what and when. Item [3] becomes a real nuisance if/when there’s a need to consult the list archives to verify a consensus decision or review the development of things such as policy proposals.
