Text tutorial

this is an awesome tutorial man!! XD it helps alot. Can I ask something though? I was wondering if you know how to have a white sort of outline outside some text thats already black, like they do in comic books, you know? Like, when the background's too dark and there's a sort of bigger font of white behind the lettering to make it visible. Do you have to put bigger white font behind it, or is there an option that you can choose to do it? >< Sorry to be a bother, but it would help loads if you could tell me!!
