CW Multicategories - Brilliant extension, brilliant support
Does exactly what it says and allows you to very easily add your articles to multiple categories. Nothing to configure or hammer into place, it just works. Support was quick and solved any issues right away. I had two problems with the extension (one with sub-category article display in parent categories, another with user group permissions in the front end editor), both of which Pavel solved very quickly and required nothing of me but to install the patched component. Definitely recommended!
