I just Made a Dollar from Selling My Story. Yay!

No. You keep your rights. I made a dollar because that was the price I set. You can charge higher if you wish, but it's usually better to start out low then charge more as your stories gain popularity. But you'll want to make your cover snippet enticing to look at so that people will want to purchase. My advice is to offer part of one story for free with a link that gets people going to your blog, and part so they can read the rest of it. Then put a second story, a story you think will likely sell up on Klatcher. I've just started this recently, so we'll see how it goes. Klatcher is another option for writing sites if you're looking for new ones.
