Done.  Now, if check_comment returns TRUE, the comment is given a 
$comment_score of 0.  If it returns FALSE, it is given a $comment_score 
of 5.  Next, it does:
$comment_score = do_action('comment_check', $comment_score);

If someone so wished, they could make a plugin that ignores the 
$comment_score given by check_comment() by simply running their plugin 
with first priority, and resetting $comment_score to zero.

After all plugins have been run, $comment_score is checked.  If  the 
$comment score is >= 5, $approved is set to 0, and the comment goes to 
moderation.  Otherwise, the comment is approved ($approved = 1).

Obviously, the value of 5 will need to be user-definable, but this 
should do for testing purposes.

Here is a basic example of a plugin that uses this:

<?php
function superheros($comment_score){
global $author;

if ( $author == "superman" ){
$comment_score += 10;   
} elseif ( $author == "spiderman" ){
$comment_score -=10;
}
return $comment_score;
}

add_action('comment_check', 'superheros');
?>


Don't hesitate to blow me out of the water if I flubbed this up... I'm 
rather new to diffs, PHP, Wordpress... everything.
