I'm always on the prowl for great online resources for writers. Below are just some of what I've found. Most (or all) should be free.
Please investigate before signing up for anything. I've tried to be thorough but one never knows. Some sites will try to get you to purchase their services or books, but you shouldn't have to buy anything to access the information.
Remember: If you post a work online, almost every publication considers it previously published.
