How Can I Add A Forum (Like This One ) To My Cs-Cart Website?

I have been needing to add a technical forum for the products I sell on my CS-Cart for some time now.

I tried to integrate my cart with phpBB and a couple of others but had issues with single sign on for both the cart and forum

Then thought... what does the cs-cart forum use?

Thank you for your feedback and suggestions.

If this question has a super obvious answer. I apologize in advance.

Never mind.... I see it now...IPBOARD....
