improve next rules and guidelines

Changed version from "2024-06-11-v28"
to "2024-06-15-v28'.

Changed all places where a date was used.

Improved the "XXX - date/time is TBD - XXX" message format.

Removed more stuff about tweeting that we no longer do.

Added a few missing | change marks.

As we fixed a rules typo, we went ahead and merged in a few of the
new rules that were pending.
