To make links work, enclose the url (that is, the 'http://whatever.man' bit) in url tags- they look like 'url' enclosed in square brackets at the beginning and '/url' in square brackets at the end. I don't know how to make them display, but if you go to make a reply and click on the button that shows a little earth icon with a chain (12th button from left) it will make a tag pair for you.
