I have recently started blogging and have seen many blogs using WordPress featuring community forums, like those you can get at freeforums.org.
My question: How do I put forums like these on my blog? Do I need to find a web host using WordPress.org, or does the free hosting at WordPress.com work?
Sorry if I sound like a n00b, but all answers will be appreciated.
The blog I need help with is thewholereview.wordpress.com.
