Hi Sam, Michael, Thanks again for your interesting questions about KPIs during the meeting. Always glad to be able to learn something new wrt. business marketing (e.g. USP, etc.) ;)
the link disappearing is annoying; but IIRC we have no E-mail attachments on-list.
The reason behind the "link disappearance" was because an erratum/updated version was published later on invalidating the first/previous link in the thread you mentioned :) cf. the updated version  with the proper Nextcloud link.
=) this has been quite widely shared; but we can always do more to communicate better; clearly.
