Dynamic Portal

[stevenbl]

I would like to create a dynamic portal page based on user role.  We would like the following scenario.  We have reports 1,2,3,4,5,6.  When User A logs in they see reports 1,2,3,4 on the portal.  when user B logs in they see 1,2,5,6. 
Another option is to create a multiple paged portal where one tab would be 1,2,3,4 and the other would be 1,2,5,6 and I would need a way to make one tab or the other tab active when it runs based on the user.  I have looked all over for pieces of this so if you can tell me the key words to search for please let me know.

Thanks,

Steven
