Hi :) Dohh, I sent this as a pm rather than to the whole list. So I've had to forward it.
I still don't understand why we want to push people's replies off-list. Off-list means the replies are not subject to peer review and makes it difficult to know whether a question has been resolved or not and it's impossible to look back over old solutions that may still work. Hey ho, grumble done ;) Regards from a Tom :) ---------- Forwarded message ---------- From: "Tom Davies" <[email protected]> Date: 29 Aug 2017 02:31 Subject: Re: [libreoffice-users] To make a graph To: "Regina Henschel" <[email protected]> Cc: Hi :) > As Regina and Brian say there is something crucial missing. > > I think "time" might be missing.
