I have (and all of us have) a table called wp_users. There is a cell in this table called "ID". It has an auto-increment option. Can you help me and tell how can I change the last number of this auto-increment option.
For example, I have 14 real users. When I tested my site I created 5 test-users (just fakes). So the last user (fake-user) had an ID equal to 19. Then I deleted them. And now if somebody wants to register, he will get an ID equal to 20. But I want him to get an ID equal to 15.
Where I can find the number which is used by auto-increment option in MySQL? Or how can I reset this number?
