I don't have time just at the moment to address all of this but I would like to request that we NOT start another mailing list. I want to discourage this because once two mailing lists exist to which BFAV traffic can be sent then the BFAV server must subscribe to both lists. We will very quickly find people sending traffic to both lists and then it will become necessary to start checking the history of received messages to be sure that a new message is not a repeat. I see no reason that posts that do not need to go to the mailing list can not be perfectly well archived within Bert's bug/fix archives and within the new BFAV server. I haven't done the work to accept such messages directly into the BFAV yet but it's just a matter of a few minutes to do so.
While on this subject I would like to request that we adopt a more intention revealing method of indicating that a message is intended to be archived into the bug system than the List-Id: header. Perhaps something like
X-Squeak-Archive-BugFix: Yes
Additional data, if needed, could be appended to this as desired.
