Ideas for included apps

Django leverages user made apps to create bigger and better projects. Here is a list of a few that I think we should use.

-django debug toolbar (This will help with development. Produces lots of debug info)
-django-reversion (This is a revision system for our models so our data is backed up.)
-easy-thumbnails (This app allows us the resize any picture. Maybe profile pictures? Seems useful for future features.)
-tastypie (Extends our app to a RESTful API so others can use selected data and services)

You can find many (and I mean MANY) more apps at https://www.djangopackages.com/ or through google, so keep the app ideas coming =).
