Calculated Risk has graciously lent his template for our use, which I think is a winner.
There is no good time to change the old template to new template. There is also no way to save the old comments as notified by haloscan and blogger. The old Angry Bear html is also much too different from current languages to translate.
I apologize for the inconvenience. You can save your comments and put them back in after the change today.
Update: Comments saved against all odds.
