okay, it sounds like you're trying to post a listing in the wrong area.
To post a listing, you have to click on the tab that says Listings. You enter your info, and about 2/3 down the page, there's a place that say's something like, "select template".
click on that link, and a box will pop up. Pick the template you want (you'll probably want to explore a bit)--then click Done (or ok? Can't remember the button)
when you're done you can preview it--you'll see it looks totally cool.
