Question: Is this community also for people who are writing non-fiction, or is it only for creative writers?
This community is for creative writers, but so far I've been allowing questions about non-fiction because it's not causing any problems to do so. I don't really care what you're writing as long as you're writing something. So the answer really is "it's for questions for creative writing, but questions for non-fiction are let be."
Keep in mind, though, that this will change whenever these posts start to bug me. That probably means if there start to be too many of them or if I suspect people are using this community to cheat on school work.
