You might want to keep a VERY few messages. You might want
to preserve them from the ravages of time, decay, and
destruction at the hands of my team, known as -
Message Unweaving Anonymous Horrendously Aggressive Helper Agents.

But how?

You may now preserve messages from my team, so:
MSG PRESERVE 3 (or whatever the message number may be).

Once preserved, a message will not be dragged off into
a Weaver's perdition, unravelling all the way. No, a preserved
will continue, even if it is more than a couple of Achaean
years old.

You will see various new ways to manipulate messages that
have been preserved if you simply chant the power word: MSG.

In the meantime, know that I will be unleashing my team soon,
though no earlier than three Achaean months hence. Beware!
And be ready please.

As for precisely what that means - it means that older
messages - messages at least 30 Achaean months old -
will be candidates for destruction by the team. The
sorts of messages handled by MSG DELETE DECAYS will
be prime candidates as well.
