could you have an article appear in 2 locations?
for example the article about terms exists in legal directory, however is accessible through articles folder and legal folder?
www.mysite.com/articles/stuff_about_terms.html
www.mysite.com/legal/stuff_about_terms.html
for listing you can split it into legal etc, so its all subdivided
but always reference it through articles directory?
both links would take you to the same article though?
does that make sense? does that help?
