MSDN has a web based news reader for all the microsoft public newsgroups at http://msdn.microsoft.com/newsgroups/.

It is mostly Javascript driven. So if you want to copy an URL for a post, you can't right click and choose “Copy ShortCut”.

But if you scroll down to the bottom, there is a link “Copy URL of this post”. Click it and the URL will be copied to clipboard. Now you can paste it.

Edit: Somehow I forget to add the most important part of this post -- how to copy url of the post. //shame. Add it
