Thank you, Jeremy, both for producing those reassuring stats and for<br>
managing the transition. The change has been much less disruptive than I<br>
was worried it would be (even though I considered it necessary from the<br>
start) and much of the credit for that goes to you for the careful way<br>
you have planned and implemented the merge. Nice job!<br>
<br>
