If the policy needs updating I really hope one of you will take on the
project and submit suggested changes in the form of a policy proposal.
There are a number of us on the AC who are more than willing to help and
shepherd it through the process.  The great thing about the policy process
is that if you don't like a policy you can take action and fix/change it.

Thanks!
