Rover and html
This is how to produce a link :
[a href="http://www.chron.com/disp/story.mpl/space/6203432.html";]The Rover[/a]
If you replace [ by < and ] by >, this is what you get:
The Rover
And you can click on HTML preview (above, right) if you're not certain and want to check first.
When the url is proposed without the html link, it takes 7 more steps to see the link than if you could immediately produce the link.
