Hi, at the picnic it was mentioned that you guys are looking for an alternative to using dropbox to share files for direction. Depend on how large the final file is, may I suggest using GitHub to store the files? It's free and is used by many many people (especially people in tech) to store simple informations like texts and wikis, as an example, Open Source Society University Computer Science course for people who want to self-teach themselves into computer science can look at the information here which is stored on GitHub. As long as the files aren't over like I think a few hundred megabytes, it should be fine to store on GitHub.
