In short: I'd like my post URLs to have the category URLs as a base. For my blog, the category should be ("blog" is a category):
site.com/blog (lists all blog posts, site.com/blog/page/2 is page 2)
and the post should be:
site.com/blog/55687/post-name-here
Or, alternatively it could be something like site.com/content/blog and site.com/content/blog/5565/post-name-here. But it makes sense for users to be looking at the blog and then when they click an entry, they go deeper in and the URL base stays the same.
Thanks for your help.
