Following the rules set in place is a good place to start. If you keep on topic, follow the rules, and have a positive attitude. Great start taking the right step forward to make your experience more enjoyable not only to you but to others.
Secondly, When in doubt, Use a mediator. With the mediation system, finding a mediator is not only the safest way to trade but it’s extremely fast to get a mediation going. Wait time is fast and easy experience not only for you but for your trading partner. Best way to avoid getting scammed.
Lastly, As stated in post #2, there is information for the trusted tags/mediators. Here’s one of the quotes I have found from that post.

We at d2jsp reward members who have displayed good character, honesty, integrity, and activity on the forum with this special rating.
The characteristics of this member can be described as generally liked and respected, helpful, honest, ethical, outgoing, active, and friendly.
Simply being a good trader is not enough, more importantly it is a philosophy of helping others, being tolerant, following all forum rules, and subscribing to the golden rule; "treat others as you would like to be treated".
We all have problems, but it is the method that these members use to find the solution that is noticed by the site. The ability to overcome personal differences and continue to create a positive environment throughout the forums is perhaps the most desirable attribute of these members.
Nobody is perfect. But following the golden rule “treat others as you would like to be treated” goes a long ways. Remember, when trading for your safety and theirs, use a mediator. It’s free service. Cannot beat that :). I feel like the system we have in place works. A vouching system, idea might seem like a good one, but it has many flaws and can be easily manipulated. And it can be abused. Potentially creating more harm then good.
