As a riders rep for Class B I get very little direct communication at all from the riders, I do get copied in on the desmodue emails but their is nothing to stop riders either sending me a U2U or email or even a phone call.
And if I can answer any questions I will, if I can't i'll suggest emailing the RC by the usual route in the hope that someone else can answer it.
My Answer to the question asked at the top of the post is contained in the sixth post down from the top
