Cannot Change Registration Page URL

Hi,

I can't change the registration page URL that the user will click on upon receiving the email, because in the form ("Place here your 'Create account page' URL") when I change it from the default value, and hit save.. it says "the configuration options have been saved" but the default value is still in the form field.

For example, i'll change it from "http://localhost:8888" to "http://localhost:8888?q=user/register" hit save, and it will go back to being "http://localhost:8888."

Also, is there away for when I'm sending out the messages with the codes to be able to send the message to more than one user at once? (IE. being able to enter more than one email, and seperating them with commas?)

Thanks,

Jon.
