We trade best answers with each other. If you want to trade, post a question asking people to trade, and let them respond. They can say how many (usually in increments of 10) and post questions with your name as the question. You can answer any way you like (a thank you is generally appreciated), and bump the questions (it gives the poster points, even if you're out of bumps). Then you post the questions for them. They answer, and you vote up their answer (gives them points too), and give them best answer. Sometimes other people jump in the dump answers, but it's courteous to save the best answer for the person you're trading with. Over time, you'll find people you can have ongoing trades with.
