If you do not read this, don't bother adding me.

Make ABSOLUTELY SURE that the person you are trading with is WILLING TO USE A MIDDLEMAN.

Process:

Make a group chat. The buyer and the seller both do NOT need to be on my friends list.
Seller trades me the item(s).
Buyer sends the money to the seller.
Once the seller confirms he received the money, I trade the item to the buyer.
The person holding the item ALWAYS initiates the trade.

I will not middleman for people marked on steamrep.

Remember that using a middleman does not prevent chargebacks. This service is merely just to ensure that the buyer gets the item and the seller gets the money safely, but not to guarantee the person will not chargeback.
Do not add me "for later," or to "have me on your friends list."
When you add me, make sure you and anyone else having anything to do with me are prepared and ready.
If you have already found someone to middleman, please delete me from your friends list.
Remember to check for impersonators before making any risky trades with me or using me as a middleman.
