Someone sent a Google Doc link to a number of collaborators (https://docs.google.com/file/etc [Broken]). I want to edit it so that everyone can see my input, how should I do it? I've done File>Open with Google Docs, but then it's only in my personal Drive. If I follow the original link again the file is not changed. How should I share what I've done? Of course I've asked colleagues for advice, looked online, but I can't figure it out! It's giving me a headache (apparently I'm getting old, technology has caught up with me ).
