I see Trevor predicts that the BARC is likely to be sticky about paperwork being correct and complete. In my case, although not planning to contest every round, I've had confirmation of my BARC race membership, have registered on-line for the Championship, have received my race licence from the MSA & also sent off my C2CVRC membership renewal application about six weeks ago. Which is the only one I haven't received yet. Be pretty ironic if the BARC non-started me at Silverstone because I can't prove I'm a member...
Exactly the same circumstances as my own, Frank. Apart from the online bit.
