The wireframe is meant to be a simple yet fairly accurate representation of the final site layout, so if you do not require certain elements such as a header or footer in the final web site, there's no need to incorporate them in the wireframe.
Based on your description though, I think you will still need a wrapper container, main content and sidebar containers at the least. And keep in mind, as this is only a graphical representation, you can always change things up a bit by the time you hit the coding stage. You're also early in the game, so things may just change as the site/design evolves.
I hope you're enjoying the movies.
Wow, thanks for answering my question. Yes, I certainly am enjoying them. I
am taking on a project that several have told me I have no business doing as
I have no experience (and perhaps they have a point) but I have just been
taking it step by step, following the directions closely with person
variations in style/content etc and so far I feel ok.
You are very welcome. Kudos for pushing yourself and good luck! :-)
