Actually it is not a trading market at all.
You shouldn't be upset about the community asking for something as simple as an introduction. Its just so we can maintain a good community of people that we all can be somewhat familiar with. You would also be surprised of how much spam shows up here from anonymous users, so most of us would at least like to know that you're a real person before engaging in monetary transactions with someone who has only posted once since 2012.
So in your opinion we are suppose to trust you with trading one of ARE units with no info from your part??
