Thank you very much, Chris!  We'll discuss here, and I'm very much
looking forward to it.  Would you like us to keep you CC'd explicitly on
the review process, or will you be following it on-list anyway?

More soon; I just wanted to give a public "ACK" response since your mail
sat in the queue for a bit (sorry about that).
