When a user logs in, there are five buttons along the bottom of the page. When they click the first one; 'home', they can view their own wall feed where questions that they’ve answered will be displayed. 

The second button is a users inbox, where you can view incoming and sent chats or questions.

The third button will give users the option to create new content, where they can ask friends and the public questions, or create polls.

The notifications can be found by pressing the fourth button, and users can view and add friends via the fifth button.
