How do I send direct messages on Twitter?

[Andrew Z]

Hi,

You can also send direct messages from:

* the reply icon attached to messages in your direct message inbox
* the drop down box on the direct message inbox page (please note: this is a random selection of people who are following you, not the complete list. If a follower's name is not on this list, use options 1, 2, or 4)
* the status update box using the direct message command: d + username + message

If your reply to a tweet, the person could see this if he/she already follows you, and in such case, all his/her followers clould see(but if you follow too many people, you might miss a lot of updates if they came out at the same time), or the person must click the @username on the sidebar to see your reply.
