How to hide the URL near the top of Profiles and Group Detail pages.
1. Determine if you wish to hide the URL on the User Profile Page, the Group Detail Page, or both.

2. If you are using a custom theme, some of the following may not apply, depending on how much you have altered the templates.
3. You can use the skin.css, portal.css or module.css file for this customization. I personally recommend changing the portal.css file.
4. Open the Portal.css file in your favorite text/html editor. The file is located in the Portals/{portalId}/ directory.
5. Add this to the very bottom of the file if you wish to hide the URL on the Group Details page:
#row1 .url {display:none;}
6. Add this to the very bottom of the file to hide the Profile page URL:
#row2 .url {display:none;}
7. Add both if you wish to hide both URLs.
8. Save the file.
9. Refresh the page, you may need to clear your browser's cache if the changes do not appear immediately.
