Hi Allen,
welcome to the forum..

Could you post a screenshot of the problem you describe.. I have just opened the newsgroup site without any problems so I'm unsure as to why your not getting access. I copied this from the help function :
'The Web-based Newsreader is part of certain Web pages and allows you to participate in discussion groups directly in your Web browser; you don't need to install or configure anything. '
It's probably a setting somewhere thats been missed? Anyway please post the screenshot and hopefully we can get to the bottom of this.
