BuddyPress.org

I am stuck. I don’t know what I am doing and I cannot afford to pay anyone. I have a very successful facebook page and I want to try to get my fans onto the wordpress/buddypress site. This is work in progress. I am not seeing how my fans will post questions on the website. Can someone help me?
http://www.areaguides.us If you want to check out my facebook page (it might help to understand what I am trying to do), it is http://www.facebook.com/fortbenningareaguide. Any suggestions are appreciated.

Thank you so much!
