Best suggestion so far is the Update only/Discussion threads like we do for SpaceX etc. Only problem is people always forget the difference and the rule is you lose your post if you post chat on an update only post (as a proven deterrent). May become a culture shock for the New Physics crowd! 
We like self moderation as much as possible, so for now let's just shelve the idea of a dedicated moderator and only return to that if things become annoying again.
So guys, feel free to start some update only and discussion threads for the main topic here. Remember to note the enforcement of update only in the update only threads.
Thanks for the suggestion. As far as I can see nobody has made a start with an UPDATE thread yet. Therefore, to test the waters, I'll start one on the "Alcubierre drive" in a moment.
Update: And, done. Moderators, please update wording in new
thread, or title of discussion, as required, thank you.

The point is to split updates and discussions for the threads that are really long and the updates easily get lost (emDrive and Woodward threads) The Alcubierre drive is only on page 7 after a decade, and there is no reason to expect anything to qualify as an update on the topic for the foreseeable future. Creating an update thread on that topic is not helpful.
