Hey breakdance...welcome to NP
We have ALL been there starting out, believe me.
It takes time to build a reputation and a little longer to build a trusted reputation. There are many instances of the domain forums being one of the first stops for stolen names to be flogged off or trying different scams.
Don't take it personal. Be patient.
As this is usually a "pay now...get the domain after payment" type business it is not without cause that people are hesitant to deal with new arrivals to the forum.
What you may want to consider, if you are doing business with a reputable, trusted member, is pushing the name to them first and having payment sent after they receive the name. This will help build your Trader Rating.
And a reputable (higher Trader Rating) member isn't about to ruin their rep by ripping you off and having their rep tarnished.
Your reputation is a lot on the forum....maybe everything.
With higher priced sales a reputable escrow service can be used to conduct the transaction.
It's an old cliche but....respect is earned.
Be patient and carry youself professionally.
Much success moving forward.
