BuddyPress.org

Hello.
I’ve just installed BuddyPress plugin and created all recommended pages the plugin asks for (Activities, Members, Groups, Register and Activate). After that I’ve created some groups and registered some users to test it, but in the pages “Members” and “groups” are still in blank.
I read the plugin documentation and, as far as I understood, these lists should be updated automatically by the plugin, but this isn’t happening.
Do I have to insert any short code in these pages to star work? Or What should I do to it works?
Thanks
