/*
Adding a user to a table with email activation. Here is the table that I am using (it is the same we use with the default settings):
====================== MySQL Dump ===============================
CREATE TABLE `users` (
  `userID` mediumint(8) unsigned NOT NULL auto_increment,
  `username` varchar(50) NOT NULL default '',
  `password` varchar(100) NOT NULL default '',
  `email` varchar(150) NOT NULL default '',
  `activationHash` varchar(150) NOT NULL default '',
  `active` tinyint(1) NOT NULL default '0',
  PRIMARY KEY  (`userID`),
  UNIQUE KEY `username` (`username`),
  UNIQUE KEY `email` (`email`),
  UNIQUE KEY `activationHash` (`activationHash`),
  KEY `active` (`active`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8;
================================================================
IMPORTANT:
Do not use this example as is. Here we do not validate anything. In your application you should validate the data first, but you don't have to addslashes() as the class does this operation.
