Reply #2: She'll go to www.twitter.com

[paparush]

And she'll login with her username and password.

Once she's logged in, she'll need to click the 'Home' link at the top of the page.

Now she'll see a prompt that says "What are you doing?" and an empty text box into which she will type her 140 character (or less) message, then hit Update.

The web service is called Twitter.

To submit a posting is called a Tweat.

140 character limit. Yes..this is MICRO-blogging.

Then, she'll want to find some people to "Follow". That is, when those people Tweet, you daughter's page will get updated with those Tweats.
