PHP can support perl regex.  So, you should be able to do something
like:

preg_match( '^[A-Za-z0-9._]+\@(?=[A-Za-z0-9_-]+\.)+[A-Za-z]+$', $from )

A straight forward back reference should work as well, it would just
be less efficient:

ereg( '^[A-Za-z0-9._]+\@([A-Za-z0-9_-]+\.)+[A-Za-z]+$', $from )

This should match Bob Brown's case and other addresses with multiple
domain levels.  Why is the URL an issue?  Does it fail the web page
check?

Sounds like this event went well.  At least one spectator liked it.
I'd be interested in hearing more about the event.  I suspect there
would be others on clue-talk who'd be interested as well.  Care to
share? :-)

Bob's ap headline was topical.  It's a positive follow up to the
the article John Kottal mentioned on clue-talk.
