Depending on how you have your DNS managed you can always do what you want with your own domain, such as add sub-domains for forums, etc. I think if you search these forums you will find this has been discussed and I believe there are some who explained exactly how they set up forums to complement their 3DC site.
You may also want to search on blogs since this has been discussed at length recently and much of the information can be applied to adding a forum. HTH
