How can I send private messages on twitter?

[Glow]

I'd like to send a message to a person on twitter but I don't know how can I send him a private message. And talking about persons,what is Cory Monteith's facebook account?
the problem is that he doesn't follow me.

You go to "Direct Message" on the right side and type in their screen name. After that you type your message and send it. Easy as that!

You can also Direct Message by simply starting your tweet with "D <username>". Replace <username> with the name of the recipient and begin typing your message. Then, simply tweet it.

if the person does not follow you you can not send them a private message. the only thing you can do is send them a @reply and everyone can see that.
