Hello, world!

I'm trying to build a little bit advanced users system using Joomla, but I stuck at one spot.

I added new field on Joomla's jos_users table, but when I wanted to get that field out, like "echo" - it didn't worked at all. Any other data, even password field I can get without problems.

Of course, I added new value in /var/www/<project>/libraries/joomla/user/user.php like this after line 40.

/**
* The users address name
* @var string
*/
var $address            = null;

What might be the problem here? Or what I did wrong, or what I didn't do at all?

Thanks for replies!
