Say you wanted to add a column called avatar to the jos_users table.
1. Add it to jos_users in the database via phpmyadmin or anyway you like.
2. Add your variable to the class JUser in libraries/joomla/user/user.php after any of the other class variables.
var $avatar = null;
3. Add your variable to the class JTableUser in libraries/joomla/database/table/user.php after any of the other class variables.
var $avatar = null;
Now just log out and back in and your variable will be available in your user variable
//gets the user variable $user =& JFactory::getUser();
//prints out the user variable echo "<pre>";print_r($user);echo "</pre>";

Tested and working in Joomla 1.5.
Please note that step 2 and 3 is quite similar so remember in needs to go into libraries/joomla/database/table/user.php AND in libraries/joomla/user/user.php
