Message Boards, IRC, etc - related to terrorist attack

[nooneofimportance]

A short time ago there was a message posted which has since become lost in the sea of post-terrorist traffic. The message contained a reference to a message board with specific threats made prior to the terrorist event.

I would be greatful if anyone with knowledge of message board postings relating to this terrorist event or future/ongoing events could post that information here.

Thank you for your help.
