I came by this open source, Mozilla-based, pre-production suite called Celtx, which is a set of basic tools to use in a movie project, such as editing, storyboarding, scheduling etc. 

The software is free and it’s possible to donate through a cause they support, Against Malaria. And if you’re into video editing, you can help directly by editing raw footage of information films, about distributing Malaria bednets, into shorter illustrative clips, which they then distribute on DVD. I thought this was a clever approach; to bundle software with the user’s specific knowledge and connect it directly to a cause.
