BuddyPress.org

You need to update the homepage in the WP Admin Settings this is exactly what I did for my BuddyPress site http://ipadalicious.com. Login into your admin area: Go to settings and Click on reading – and under Front page displays page. Then:

1. Select A static page (select below)

2. Then select Activity Stream in the Front page: drop down list

3. Then click save changes and you should be good to go.

Hope this helps.
