Christmas arrangements 2008

I am posting our Christmas arrangements a bit earlier this year. Our Boston office will be closed from now until December 22, while we all get together here in Melbourne for somewhat extended celebrations (and some serious work!). The Boston office will again be closed December 25 through January 1.

Our Melbourne office closes December 19 through January 4, re-opening Monday January 5.

Between now and December 19 all orders will be shipped out of Melbourne. From the December 19 through January 4 there will be no order processing.

As to reliability, the most important things are:
