Shouldn't that look like this??
CREATE TABLE`sites` (id int(11) NOT NULL auto_increment primary key, title varchar(70) default NULL, description text);
Anyway he's saying add a column named "live".
alter table `directory`.`sites` ,add column `live` boolean DEFAULT '0' NOT NULL after `description`
Have your users enter the data in the database. When they enter their data let the 'live' data take the default value you defined (0). In your PHP code, simply use a conditional statement that decides whether or not to display the updated title title according to the value in your 'live column'. If live is set to 1 show updated text. If its not, then do not. I'm also assuming he was suggesting that when a user submits a form you email yourself a notification.
Then run a update query to set the live column to 1.
