Adding a new user to mySQL DB with phpMyAdmin

In addition to the graphical UI provided by phpMyAdmin, you can just issue the following SQL:
GRANT ALL ON DB-NAME.* TO IDENTIFIED BY '';

replace by teh user name you want, e.g. fernandotorres and replace by the password for this user. Note that there are ' signs around the password - keep them.
