Yes, we do have forums at MTT that you can feel free to use to discuss fanfic and/or the show.  Some people asked how they work.  The databank with usernames and passwords that goes with the fanfic software we use here is not connected to the one for the forums so you have to register for the forums separately although you should be able to keep the same username and password if you so choose.  The registration button is hard to see but it is at the top of the page, under the more than that quote.
