Displaying Logged on User Names

I am creating a small chat room using PHP, MySQL & Dreamweaver.  Everything is great apart from one problem that I can't seem to find the answer.

The first page of the site is a login screen, which obviously only allows registered users to enter the chat room.  A successfull login moves the user to page 2, which is the Chat Room.  I would like to now how to;

Display the users name in a header bar in the chatroom, so that I can add a welcome message.

Autocomplete the username field of the database when the users posts a message.  This is to save them having to type in their name every time they post.

Also, how do I refresh the page so that if the users doesn't post a message it still updates when other users post theirs.

Any help would be much appreciated.

Thanks

Put:
<?
session_start();
?>

At the top of all the pages you need to have this persistent username.

on successfull login, convert their username to a session.

i.e.:

$_SESSION['displayname'] = $_POST['username'];

Then to display it, you would:

echo $_SESSION['displayname'];

Pretty easy..

1) you can display the logged in username using php like this:
<?php echo $_SESSION['MM_Username'];?>
You can put this code anywhere you want to show the logged in username.  

2)Have a hidden field in the 'post a message' form like this:
<input name="username" type="hidden" value="<?php echo $_SESSION['MM_Username'];?>">
use this hidden field as the username in the post.

3) The easiset  way is like this using the meta tag
<head><meta http-equiv="refresh" content="10"></head>
