CREATE TABLE `userpref` (
`id` int(8) unsigned NOT NULL auto_increment,
`username` varchar(128) NOT NULL default '',
`preference` varchar(64) NOT NULL default '',
`value` varchar(128) default NULL,
`descript` varchar(128) default NULL,
`added` datetime NOT NULL default '2003-01-01 00:00:00',
`added_by` varchar(128) NOT NULL default '',
`modified` timestamp(14),
UNIQUE KEY `id` (`id`),
KEY `type` (`preference`),
KEY `added_by` (`added_by`),
KEY `preference` (`preference`),
KEY `username` (`username`)
) TYPE=MyISAM;
