A chat link(or link to a forum thread) at the bottom of a show's page, It'd be nice if it were like the reviews page but for chatting about the show.

Just to make the site a little more user friendly so people don't have to go searching for a thread about your favorite show.

All you would really have to do is copy the reviews php, mod it a bit to store chat in a different table and remove the bit that removes your last message before posting the new one.
And maybe give users a warning about spoilers("Warning: This page may contain spoilers blah blah blah")

We have an IRC chat room. Search the forums for the IRC Chat thread and you can learn how to enter. I will see if we can add a link to it on the homepage. Thanks for the idea.

Your request is actually already on Admins to-do list.

However its assigned priority is not as high as that
which is currently being worked on.

The idea is that a "spoiler" thread can be accessed
the way you suggest for discussion of the latest
happenings within a show. Anybody accessing it will be
warned that the thread is primarily for that type
of discussion.

Ordinary general discussion of a show to remain in the
open forum for such as airing dates where to find torrents
and so on. So that those who are 'catching up' or wondering
whether to start watching a particular show will still get
the information they need without reading spoilers.

Oh right on! It should keep people from chatting in the reviews box as well.

Yes there is that as well.
