mysql user

[RazorOnFreeBSD]

Hi everyone,

I maybe didn't see something, for sure it's a dumb problem....
I installed MySQL 4.0.20 from sources downloaded on MySQL website and then I checked before adding my "mysql" user on the box if there was one .... I never installed MySQL before and I already have a mysql user but I don't know his password.....
What should I do ? Uninstall / ReInstall MySQL ? Delete user "mysql" and create another one ? or is there an obvious first password to change I didn't get ?
I'm a little bit lost there... even if it's not an obligation to have this user named "mysql", it's easy to use everyday!

Thanks.
