Do you need CS6 to have a computer forum in Dreamweaver

I was told by an Adobe Live Chat Representative that I needed to upgrade from CS4 to CS6 if I wanted to add a forum to my website.

When I tried to learn how, I found an earlier forum discussion that said you can't make a forum directly in Dreamweaver unless you can hand-program in PHP or SQL. Instead you have to use an outside software package (such as phpBB) and integrate it into your existing website. So I need to know:

1) Can you create forums using the tools available in CS6?

2) Can you integrate a forum desgined using a package such as phpBB into a Website designed in CS6?

3) Do I have to upgrade to CS6, or can I accomplish the same thing with CS4?

Thank you in advance for your assistance.
