Has anyone encountered a problem with using the Q&A Plugin?

If you go to http://www.easylifecover.ie/questions/how-much-should-i-be-covered-for-life-insurance/ you'll see that I've implemented my first question. I had to add it through the backend though.

Visitors from different browsers and myself have been trying to add and answer questions but the area to add content is not allowing us.

Can someone let me know if I need to adjust issues in the discussion area of wordpress or if there's someone I might have missed during installation.

Cheers, Cian
