Notify users that "someone else is posting" I don't know whether this would be difficult to implement, but it would be nice to have a feature where you can somehow know that someone else is in the middle of writing or editing a post in a thread, so as to avoid "stepping on their toes". For instance, if I've just written a post, and then I see a need to edit it, I may write a follow-up post instead if I know that someone is writing a post, because there's a chance they're responding to what I originally wrote. Or I may hesitate before deleting a post. Or there's a chance that someone's editing a post that I was planning on responding to, so I might hold off on it. Various things like that. The feature wouldn't need to say which users are in the process of posting, or even what is occurring, whether it is composing a new post or revising an old one. I would just like to know "something's going on here right now."
