I'm looking for a kind of "Boolean 101" tutorial. I have an old link I think Alex might have provided some time ago that no longer works:

http://newspro.hypermart.net/wildmat.htm

I tried a Google search, but didn't come up with anything really basic. Has anyone a link?

Thanks.

Spoke too soon. I found Alex's page by changing the address to the current domain.

But any others would be appreciated.
