I've helped with this wiki and can report it's chock-full of all kinds of great stuff. Please take a look. And if you're up for it, Liberty Hall is a serious writers' community where the focus is on writing (typically through several weekly or monthly challenges, a weekly timed flash challenge where you have 90 minutes to complete a story based on a trigger given to you, polish challenges devoted to polishing existing work, and short story challenges that work on longer time horizons, to name a few.) It's not for everyone, but it's a serious community focused on writing, and I've personally benefited from the knowledge and resources available there, and the natural kick-in-the-pants that comes from seeing others write a story in weekly flash challenges week after week after week.
