How about Googlesearch for TR?
I know that it is somehow possible to have the Google software implemented on a site and configured to search the site topics ahead of world wide searches. The perfect example of this is at sourceforge.net. That web site is a repository for open source projects. If you enter a search on their site search function it will create a two part display. The upper part is, I believe, from Google Ads. The lower part is a site listing of hits for your search. It's really great. I think that TR would help people looking for anwers to questions that are perrenial favorites by implementing this feature. It's even possible that Google pays sourceforge.net for hits on Google Ads. I don't know.
Anyway, this Google search feature found on sourceforge.net is exactly the kind of thing that people could use when they are wondering why their NT domain isn't working with their new Windows Server 2003 PDC, since that question is asked, in one form or another, about once a week.
