How can I change the Message at the top of the Registration screen?

The one that says:

*Note: Membership to this portal is Private. Once your account information has been submitted, the portal Administrator will be notified and your application will be subjected to a screening procedure. If your application is authorized, you will receive notification of your access to the portal environment. All fields marked with a red arrow are required. - (Note: - Registration may take several seconds. Once you click the Register button please wait until the system responds.)

Thanks,

I appreciate your response to my question.  I searched the host language as you suggested and was unable to find the User Registration Message.  I may not have been clear in stating the location of the message appearance.  It is at the top of the Registration page (I am referring to it as a page, although I am unable to find a Registration page).

And other thoughts on this would surely be appreciated.  I know it is hidden somewhere in the bowels of DNN.

Thanks,
