Good catch.  Turns out it was already imported up top!

As a note, I've been reordering imports into three sets, to follow django convention: first, python and outside package imports (first imports, then from...import), second django imports, and third project/app imports.  

I read this off of the django site or djangobook.com; I couldn't find the link just now :(  But I find these two conventions (three sets separated by empty lines, and each set ordered to import and from...import) to give a much more organized feel to imports, and helps make the imports more readable for those less familiar with our project and app structure.

Let me know what you think.  I've been doing this for the past few days, any time I have reason to touch the imports.
