I think this thread has gone well off topic! But this is the problem when anybody suggests formalising anything.
Dave M3XIE had had a chat on GB3VT repeater with two mobile stations - M0TUB/M on the way home from an activation, and myself. It was very enjoyable, as SOTA was the main topic of conversation.
FWIW, I will be QRV on GB3VT as M1EYP/M most weekdays sometime between 1430 and 1700z. I always enjoy a chat about SOTA if anyone wants to catch me on there.
Cheers,
Tom M1EYP
