MySQL ID

Hey php-general@lists.php.net, I have few users in my small page. And it goes with ID numbers. I did auto increasement. And i think all the settings are ok. but in phpMyAdmin it shows ID numbers starting from 5 and i have 10 users so when i deleted row(user) with ID number 9 i have id number going like 5 6 7 8 10 .... . So i have like two questions. How to do that autoincreasement started from 0 and how to do that all id number where by order without missing some of them when i delete them. Like how so make that ID number 10 to be number 9 in the list..and all other number to go down by one. Is there simple way to do it? P.S i am so sorry that my english is weak. I am just learning ESL ir highschool :).... Thanks for helping everybody :------------------------------: Have A Nice Day!
