To get sites that are linked in to a website that you are interested in, do the following:
1. First you need to go to a metasearch engine. I like www.dogpile.com
2. In the search feature type in the word link: and drop the www. from the website you are interested in referencing.
For example, using www.happen.ca as a target, I went to dogpile and typed in link:happen.ca and did my search. Up popped various references to Jim Geraghty, HAPPEN, etc.
Let me know if you are having any difficulties.
