Maybe I dont understand this. But I tried installing a pal box yesteday to mysite as per gardner instruction and it worked fine.
Now I was wondering, if the case only adding an html code after the <<COMMENT code. Than why not adding the html code one normally get from those news feed site and placing it as if your placing a normal html code. Than that I think should work exactly the same and get the NEWS FEED accordingly and placing it in the pal box of your choice. OR AM I MISSING SOMETHING
