new user privileges

[Stonix]

Hi,

I'm new in mysql admin. I have question on create new user.
Suppose I have created a database called 'abcdb'. Now I want
to add a new user with full privileges on only 'abcdb'. How
should I do? I tried 'grant all privileges on abcdb.*....'
but still the new user has the superuser privileges. I only
want to add a new user of a developer level. Anyone can help
me out for this question.

Thanks in advance for all reply!
