upon reading this thread again, and again, i see the difference in original vs my question. i have also read several VMB threads.
that said, i wish to have one site with two distinct sections/functions. one user registration.
the masthead will be the same for both but the nav menus a bit different, hence the need for a header1 & header 2? anyway that is what i have going at present.
Section one = e-zine, a blog in a magazine format where posts are stories, longer posts, with comments, forum, a sidebar 1.
Section two = item finder, where posts are shorter, possibly an excerpt, links to this and that, a sidebar 2.
the conflict = a) big difference in post content between section 1 & 2 and b) how to categorize, wishing same name but residing in different sections.
note: concept #1 = two categories with same name to keep visitor in the appropriate section. i thought the categories might have slightly different constructions - " buttons " & " buttons> " each with unique ID.
i currently have 60 categories, 6 parents with 10 children each, for example. which would double categories in concept #1
note: we are totally in agreement on how to use xhtml, css, etc.
i am not a programmmer. however, i can now modify this and that but cannot create this and that. i have access to a former student who is pretty good with php and css though does not code with wp in mind. strictly phpmyadmin and on the server, which keeps her solutions out of wp-admin. so that's a problem in my mind at this early stage of development. maybe its not an issue.
bottom line, i don't know the " structure models " options available. is it simply one blog with one database. two blogs with one db? two domains with one db seamlessly working together. note: only one domain to be bookmarked, seo target.
