I presented this not only for future reference for those who's requests might fall under this list, but also to give you an idea of what I'm dealing with even without requests.
I'm saying this not only this, but as a reminder for the sake of all fan fiction writers: they are human beings with their own lives. They do not have any obligation to update their stories for your sake. And definitely don't write reviews or pm's urging them to "hurry up and get the next chapter out" or "get this one over with" for any reason whatsoever. You are only rendering yourself asinine in their eyes, and they will most certainly not be any more motivated to continue their work. I have not checked my own reviews in a while, so I'm not saying this out of my own annoyance because I received any such messages. I simply felt the need to say this on behalf of other writers at the time I wrote this.
