sorry, I didn't obey the rule here, I'll try again by inserting the proper formatting for these posts. 
      $m = WWW::Mechanize->new();
      $m->get($url); # $url is some home page
      @links = $m->links();
      for $link ( @links ) { 
        &follow;
      }
sub follow {  
  if ($m->follow_link( url_regex => qr/contact/i)){
      print "$link->url\n";
  }
}

I tried the "follow" subroutine, thinking that if the if statement was false, it would return undef, but instead, the first link it tried to follow, which did NOT contain the string "contact" just crashed the program with the error message "Link not found at c:\websites\bla_bla\my_perl_script.pl". Why would mech assume the relative link was something off my hard drive instead of from the first fetched page????
