If you log in as the admin, then go to your Users page, there are boxes for changing the password. If you want to change the login name, I think you would need to do that in phpMyadmin. You can change what displays on the blog though, if that’s really all you need.
You can’t change the passwrod for the admin. The program has to change that for you. Is that correct?
I wish you had more control over the look of the blog page. Can I change it?
Is this an open source script? If it is can we take out the all credits and the name Word Press from the blog site?
I might be wrong. I will have another look at the control panel. But as far I remember, you could only add additional users and change their password only not the admin or administrator’s!
