Another long list with lots of interesting themes to inspire. Some have fairly short deadlines, some give a bit more time. Most are for anthologies or magazines, but there's also a list of competitions at the end. A few here strike me as possible but I don't have any current projects that fit. Still, I might pick one to target and try to write to that theme.
