Thanks for the theme capability! It makes a great way to change the blog over to a new design for a while... at http://www.2020hindsight.org/ I am "liveblogging" the development of the atom bomb, and am blogging like it's 1945 (yes, it's a 60-year time shift).
Since this is the week preceding the first atomic bomb explosion, there are (and will continue to be) lots and lots of posts.
Let me sing praises to WordPress's ability to time stamp posts in the future. If not for that capability, this would not be possible.
