Microsoft have opened up the Windows 7 Answers forum.
Which I have to say semi-replaces the old newgroups, well not that there are any Windows 7 newsgroups yet. The old battle between web forums and NNTP looks like its heading the way of the web, I know in my opinion that's largely down to how bad the latest version of Windows Live Mail is at handling newgroups, no where near as good as Windows Mail or Outlook Express.
Anyways enough rambling hope to see you on there with your questions.
