Hi Doug,

I've yet to review this, but just wanted to let you know that we've
started on it and also testing. We'll get back to you with some
feedback and results soon.

We had also been looking at some of these same and related issues so
we want to make sure everything we've done is compatible with your
changes and is still working ok too.

Regards,
John
