The old address, Walt.Gregg.Juneau.AK.US, is eventually to be changed to this new address. The reason is that the .US domain has been taken over by scammers and spammers -- some 25% of it, in actual fact. But changing email and web addresses is a Royal pain. So it may be quite a long time before this new site actually contains the content. In the meantime please visit the old address.
