If you’re new on the forum, then anyone is a stranger to you. That’s true. So again, take some time to explore. When you’re new member, you’ll notice the older members who are selling or buying items. And how to recognize the most reliable among them? Always ask for background from the forum moderators or administrators if you’re not so sure. But good traders always respond in the trading topic, leaving the price or another offer (item, account,..) if they’re exchanging items. Also, in good trader’s topics you’ll always find others’ responds before that topic is closed as Sold.
