People trade best answers. If you want to trade with someone, post a question asking if someone wants to trade and how many (usually in groups of 10). You post the same number of questions for them. When they answer, you vote up their answers, and then give them the best answer, and they will do the same. When they post questions for you, you answer them any way you want, and bump their question. Always vote up and bump, even if you don't get credit for any more for the day, because the person receiving them also gets points. You can also post questions offering a best answer or some votes up. Keep an eye out for these to see how people do them.
