I need a Q&A website built that will allow users to post questions, answer questions and search other questions and answers. They will post questions based on category and will be able to add other users/friends to their feed where that persons questions and answers will display. They need to be able to select public or private when posting a question. They will be able to sort out their friend into different categories/circles. Users need to be able to log on using other social network login such as facebook, twitter etc. A home page similiar to [url removed, login to view] and [url removed, login to view] is what is wanted, something were the users get to the homepage and are given the option to log in, join and also view a graph/animation that will help them understand the concept. Users need to be able to earn points for asking, answering, getting likes for their posts. On the users page there should be a feed display for all their friends posts as well as questions from the categories they are following.
