Generally I think that no links should open in new windows. Firefox has a wonderful feature where it opens a new tab instead of a window like IE. The internet is full of links. It would be stupid to have ALL external links come up as new windows. That is why most people don't do it. But if its the cretira, we have to put it unless we want to be docked 5 points. To me this is just another stupid rule you gotta follow but you know its wrong.
