Hey, Twitter,

I can't find out what "retweeting" is/does. A user asked me to resend a message out to everyone who follows her and I can figure out how to do this or if it has anything to do with retweeting. They might be two separate questions.

I don't get the whale and the birdies (oh, right "tweet"), but I love them, even when you're down.

Thanks!
