What about TrekMovie.com forums?
I am glad you asked. TrekMovie obviously has an active community for article talk back, but we have held back on traditional forums. But in February we will be opening a new community section of the site. The first step was taken literally this afternoon by signing on with a new hosting company who will be able to handle the growing traffic for the site (the new provider handles huge sites using the same technology, like perezhilton.com, so they can handle us). More info coming soon.
