Dreamweaver has got a fantastic template system that allows you to
create and make changes to your various sites. If you haven't done
anything for nearly 4 years then you will need to start pretty quickly
to get back into habit of doing some gainful work.
I suggest read this article to get a feel of of what is currently involved:
I agree. And the only configuration that will let this work as originally described would be the subdirectory method in the original post -
Your Template would then be able to manage the 'boilerplate' layout in each of those subfolders within a single site definition.
As a cautionary note, don't fall for the siren call of using either nested Templates or multiple Templates for the site. It's easy enough to make this all work with a SINGLE Template, which is much more manageable from a maintenance perspective.
Thank you both of you for quick reply. It's appreciated. This is good news and I only wish we had all these capabilities of Dreamweaver back in old days. On the other hand that keeps everything exciting and engaging. Cheers!
