Usually all the forum are divided into: threads and posts.
Users create threads and then post messages to discuss them inside those threads.
You can create a website that consists of a forum only, or add a forum to the existing website.
Nowadays you don't have to a website developer to create a forum, you can just download a lot of various free forum scripts “Free and Open Source Forum Software” install it and enjoy your online forum.
I recommend using a Open Source Forum Software because you will get better support in comparing with paid forum software, and usually Open Source Forum will have a lot of plug-ins and mods that will help you to make you forum more user friendly!
