Preg_match Matching only on a new line?

[MTGDarkness]

I have this code:

PHP Code:

$mepattern = '/\/me([^\r\n]+)/is';
if(preg_match($mepattern, $this->post['message'])) 


It's half the /me hack that I downloaded. However, it got greedy and started detecting all /mes. Annoying when you're using URL rewrites and one of your forums is named metaboard... :down: Basically, I need it to only detect /mes at the beginning of a new line. And I am really bad with Regex. Also, what does that one snippet

PHP Code:

([^\r\n]+)/is 


mean?
