How does the PRO Q&A forum work?

[monetize-266006]

OK, so the SEOMoz PRO Q&A forum is officially awesome since the redesign. It works amazingly well guys - thanks for a great resource!

I'm wondering, what technologies have you used to make it work so well? Is the Q&A forum totally custom, or does it run on top of another 3rd-party / open source / web app structure?

We're thinking about doing something similar for our business (not in the SEO space, so don't worry
