SharePoint Ninja

Modifying the sub menu (the one that says Overview, Organization, Content, Tags and Notes, Colleagues, and Memberships) is not a straight forward process. At least not at first glance. When you go to the site actions you don't see anything for navigation.

If you open up SharePoint Designer and connect to the My Site Host you will find that the DataSourceID is MySiteSubNavDS, but you don't need to worry about that.

The trick is that the navigation page is there, but just not shown on the Site Actions page. You can append _layouts/AreaNavigationSettings.aspx (i.e. http://mysites/_layouts/AreaNavigationSettings.aspx) to the My Sites location. Then you can modify the Current Navigation and that will work (even for the personal sites areas). Easy breezy lemon squeezy.

I hope this saves someone some time!
