I have installed frameworks and enabled the captcha security check for the register page. I think it works.

But on the register.php I really would like to:

1. Get rid of the Website text field.
How to do that?

2. Get rid of the Timezone dropdown field (since time is fixed for my use (default)).
How to do that?

3. I would like to have my members register with all characters in the nordic alphabet (i.e the letters æ, ø and å as the three last characters after z.
May I just edit z -->å in the register.php?

Any help with these issues would be highly appreciated!
