I was not happy with the way the link to "parent" messages worked and I have modified a line in modules/NS-Comments/index.php as follows (the only line containing the word "_PARENT":
echo " | "._PARENT."";
Which seems to work wonderfully when I move up the hierarky: if you click on "parent" it displays the parent messages and the children thread. The problem is when I get to the first child of a message that is the direct reply to an article. If I click on the link to his "parent" I would like to get the full article and the thread of all responses, but I only get (perhaps correctly) the messages and the thread and not the article story. What is most annoying is that this page does not have a style but just a white background. Any idea why?
