I'd like to find any popular online DISCUSSION FORUMS -- which focus on
advanced search methods (such as how to do boolean, and exclusion,
searches on craigslist.org, for example).

Are there any good forums for this sort of thing?

I'm not talking about just google, but searches which may be conducted
anywhere on the internet.

Thanks!
