How to hide/show forms based on user selecting "Accept" on terms and conditions page?

Hi,
We have the following requirements:
1. User (Not Admin) visit our site and will show the terms and conditions tab only each time
2. Once he click the "Accept" radio button and click "Submit" button then shows other forms (which are tabs) to him/her.
3. If Admin login, it should show all tabs.
Please let me know how to implement it. If having code snippet that will be awesome.
Thanks,
Winson
