Configuring portal screen (Page display problem)

Hi Gurus,

I am trying to personalize my Portal Page.

My scenario is I have uploaded a Business package of CRM. Now when I am assigning the role to a user then the entire page is appearing in the left side of the screen (Portal favourite).

1) Can some one tell me how can I display the page in full width (Cover screen area)?

2) How can I customize my logon screen? Any link

Regards,

Abhishek...
