Create an account. Go to Twitter.com and click the green “Get Started” button to join. Enter your name, user name, password, and email address, and you’re good to go.

Decide what you want to say. In general, Twitter messages, or “tweets,” answer the question, “What are you doing right now?” But you can also post a link, express an opinion or reaction, or pose a question.

Twitter keeps things short and sweet: Messages can be no longer than 140 characters.

On the home page, type your message into the box at the top of the screen and hit “Update.” Congratulations! You’ve posted your first tweet!

If your tweet is intended for one user in particular, type the ‘@’ symbol followed by that user’s screen name before the text of your message.

Twitter is a two-way street. Now that you’ve posted your first update, choose people whose updates you want to follow. To search by name, click on “Find People” in the upper right corner and then click the “Find on Twitter” tab. You can follow individuals, like friends and colleagues, and groups, like news services, organizations, and nonprofits.

People may be listed under a screen name that doesn’t match their real name.

Once you’ve found someone you want to hear from on Twitter, click “Follow,” and you’ll receive their updates automatically. People you already know will often reciprocate and start following you, too.

If you have a Gmail, Yahoo, AOL, Hotmail, or MSN email account, you can import any contacts that also have a Twitter account. You can also invite someone via email, or scroll through a list of suggested people.

To help people find you, fill in account information under “Settings,” such as your location, real name, and a brief bio. You can also add the URL of your web site or blog if you have one.

If you want to restrict your Twitter updates to only those who follow you, check the box marked, “Protect my updates.” You’ll maintain your privacy, but you’ll limit your reach. To get the full Twitter experience, leave the box unchecked.

You don’t have to be online to use Twitter. No matter where you are, you can stay connected with your cell phone. On the “Devices” tab under “Settings,” enter your mobile number to receive and post Twitter updates via text message.

Twitter doesn’t charge for text messages, but your wireless provider might. Make sure you know the details of your messaging plan.

On the “Picture” and “Design” tabs, customize how your profile appears to others by uploading photos and choosing background themes.

See what people on Twitter are saying about subjects you’re interested in. At the bottom of any Twitter page, click “Search” and type in a name or topic. Or, either below the search box or alongside search results, check out what’s generating the most buzz by browsing through “Trending topics.”

You can post updates from the web in the update box, via text message, on your cell phone’s web browser using m.twitter.com, or from any third party application. Apps are available at twitter.com/downloads. The more updates you post, the more people will follow you. Now get tweeting!
