Hi Richard,
Additionally if I were the actual proposer of a policy, I would be unable to contribute to that (or any related) decision-making-process. Which is why I'd be a lot happier if other participants would consider making proposals.
Don't worry about this. That's one reason why a working group has more than one chair :-) We sometimes have this situation in the Address Policy Working Group. Look at proposal 2010-04 for example. Gert proposed it and took part in the discussion. I don't take part in any discussion so I can make an objective decision on whether the working group reached consensus ore not. And then the whole working group chairs collective checks to see if I have followed the process correctly and that my decision about consensus is correct. You can write a proposal. There are enough safeguards to make sure that the policy development process is followed in a fair, honest, clear, transparent, etc way. Looking forward to your first proposal! Sander
