I've had more correspondences from the sail mail guys......goodness what amazing assistance from them!!!
This is their take on small emails....besides masses of info they sent on how to get the system up to speed....they really care!
And no need for a comm's "blackout", personal notes are pretty small (compared to gribs) and usually a lot more useful for the crew morale
So go for it with small emails, no signatures, no attachments!
I know from being with them on their first leg this just means so much!
