Select type of listing - before clicking on the add button on the Managing Listings page, select the overall group the listing should be in - for instance Accommodations or Restaurants etc.
Long Description - This is the only part that could be a little tricky. The text you place in here will be treated as HTML code, so that you could actually create a mini web page here if you wished. Only HTML tags that would occur with in the body of the page should be used. Does this mean that if you don't know HTML, you can't enter a description here? No, you can enter normal text and it will be display, but might be repositioned and the paragraph spacing changed. You can avoid this by placing the tag <pre> on the first line and </pre> at the end after all of your text. This will maintain the formatting as you typed it. You may also find it useful to precede words you wish to be bold with <b> and follow them with <.b> (End of miniscule HTML lesson) :-)
