Hi Don,
You are able to use DW site manager because you are the Admin of your own Moodle site and thus have all the rights to do what you like. How I wish I could manage my Moodle courses through DW site manager (as I used to do with WebCT).
Unfortunately, one must always remember that in a number of situations (expecially with educational institutions), 'simple' teachers have far less rights than Admin.
>... Your Dreamweaver code will be stripped away. This is a good thing for the new or in-experienced user. Pros can disable the wysiwyg editor (admin/editor) and paste DW code as raw html.The stripping away of DW code (well, some of it, anyway) may be a good thing for new/inexperienced users. It is probably very desirable in places accessible to the students (i.e. forums, etc.). Unfortunately, in current versions of Moodle, there is no provision for pro teachers (which I consider myself to be 
) to do what they want, because far too much of the power resides in the hands of Admin.
