Subject: [PATCH] www: make mirror instructions more prominent
Date: Tue,  8 Sep 2020 08:29:14 +0000

In order to fight the misconception that public-inboxes are
centralized, anchor "#mirror" to the clone instructions and
place an emphasis on "mirror", not just cloning.

While we're at it, better describe multi-epoch -V2 inboxes,
since some users do not seem to realize epochs consist of
different data.
