Yahoo! is beta testing a new tool. It is called Site Explorer and can be found at:
http://siteexplorer.search.yahoo.com/
It will search your website and will list all of the pages it can find and
all of the links pointing to it.
This is a good tool to make sure all of your pages are getting indexed
properly.
Thanks to RockyMoore for this tip in the asp.net forums.
