My one reservation in this process is that I am concerned about the subscriber list and I am not sure how we want to treat this. I view this as a possible privacy issue. For example, if we were to migrate to a new mailing list, it's important that list subscribers are not disclosed. At the same time, some people rely on this mailing list for important announcements maybe even security announcements in some situations. I'd appreciate feedback on what people think about this particular issue. Since the mailing list is not reliable anymore, please remember to cc the feedback to me directly.

In the mean time, here is an archive of the mailing list content including some old timestamps in the opentimestamps format for some of the older content:
