Where does one go to make the links to people's websites in the Comments section dofollow ones? If I'm not mistaken, a rel="nofollow" Code (markup): or rel="external nofollow" Code (markup): must be removed from somewhere... Also - if not in the same place as the rel attribute - where does one go to launch those links in a new window (i.e. target="_blank" Code (markup): )?
You need to add a function filter for comments to remove that attribute and add the other. There are plugins for removing nofollow, not sure if there is one for opening in a new window.
