I read somewhere that the wordpress.org theme is not available for re-use. Fair enough, but that site -- less of a blog, and more of a community information site -- is what I want to achieve.
As a WordPress newbie, can anyone tell me what is involved in, and how to go about, configuring WordPress along the lines of wordpress.org? E.g. with multiple site sections, a section navigation menu at the top and a sidebar navigation menu for within each section, and with bloggish features like blog rolls removed?
