Layout tab

Q: Why do I not have a layout tab?
A: Those of you who do not have the [layout] tab needs to upgrade to the new blogger. It goes like this: 

template (2004)>customize>layout>design (2010)

Sean has a way to change from template to layout tab:http://notjustajax.blogspot.com/2008/06/how-to-reset-your-blog.html

Roberto has a link:

A few of you, may even have to make a legacy claim:
