For what it's worth, they never actually seem to be friendly. I constantly got emails and complaints about the old one also.
You are doing the right thing if you are clicking on "New Listing". When you do that a drop down menu should open. Are you just quickly clicking or are you giving it the 2 milliseconds that it requires for the menu to drop down. From the menu, choose "Buy Now". Which is their dumb way of saying for sale. After you click "Buy Now", a box will open for you to choose a category and etc. Before you can actually place an ad though, you need to click on the user panel and fill out your address and etc.
