Welcome to the Q&A Forum

I have a Q&A site which I am struggling to get ranking well in Google. I had a few questions 1. Should I be doing some internal linking and if so how is it best to do this? Should I go back into users questions and change certain keywords to links if applicable? 2. Should I be nofollowing the index pages ie /p1 /p2 of discussions? 3. If anyone has chance to look at the site and let me know if there is anything else I am doing wrong I would be really grateful. Thanks
