It's funny you mention that because I actually do have such a file! I also went ahead and used Basecamp too to get a sense of what could be improved or simplified. But of course I didn't even consider uploading that file and this was long before this whole debacle started. We need to trust services like Basecamp, Google Docs and the others... A lot. But we also need to be smart about that trust. A healthy distrust is definitely in order in certain circumstances.
