IMDB closed down it's message boards on Feb 20th, its a shame but can see the reasons why.

Officially closed due to 'No longer providing a positive, useful experience' and I can see that.
Hasn't been so much about movie discussion for years now, more a place of trolling, online bigotry and personal bitching.
