Good QA plugin

This plug in is easy to instal and set up. I think that it is very good at what it does but I do have two complaints.

1. It is QA, but it is not similar to stack overflow (part of what they advertise) in that there is not point system. Users do not accumulate points for participating.

2. The custom sidebar does not integrate well with my theme on mobile sites. It leaves large white spaces in the header. I’ve tried turning off the /answers page and recreated the same functionality using shortcodes; however, the documentation is rather unusable and there is only one example (the site mentions a video, but the link goes to a list of the shortcodes). The solution to my problem is that CM Answers releases a responsive version. They said this was in the pipeline in 2013, but still waiting. Once this is taken care of I will change my ration to 4 stars.

For 5 stars I would like to have a point system like stack overflow.
