Here's an alternative to IMDb!
Anyone who's looking for a real alternative to the IMDb message boards should check out this site. It has a separate board for every movie and tv show:
https://www.themoviedb.org
Too complicated.
shareHow is it too complicated? You just search for Murder She Wrote. Then you click on the speech bubble icon on the left of the poster or you scroll down and click on "Discussions" and then "Go to Discussions. It'll bring you to the discussion board of the show. Just click the green button on the left to start a new discussion.
I have no idea what the leaderboard is, but the "Forum" you see at the right upper corner of the homepage will bring you to the general forum to discuss technical issues or whatever, NOT the message boards. Those work exactly like IMDb.
