Where in my Blogger settings can I access the new Blogger template designer?and to be sure, it seemed, at one time, a bit tricky.
(Update 2010/06/10): The Template Designer is now a production Blogger feature.
The Template Designer is now part of Production (Orange) Blogger, and is accessible from the dashboard "Template" page - or the navbar "Design" link.
If you click on "Design" from the navbar, you get the "Template" page, where you find the "Customize" button.
There it is - "Template Designer".
Just login to Blogger, click on "Template", and hit the "Customize" button.
You can't miss it.
