It's just writertown.com they charge 99 cents a month subscription, but I think you get a week free. Inside the site look for the gigs link and in there are both job listings (for people looking to hire writers by the project) and markets, (publishers, websites and magazines that accept open submissions.) it's a great site. you can also post your writing related posts there, and link to your blog, or your steemit page, if you wanted. It's the only subscription site I recommend.
