In order for this to be effective, however, you would also need to limit editing, otherwise people would simply take their one post and continuously edit it to reply to other posters.
What good is a discussion board that only gives you your one initial opinion? Every argument has a dozen different sides to them, and different angles to look at them from. Limiting members to one posts will completely eliminate constructive opposing views. This is why Player Polls exist. You get a series of questions and you pick an option or you write an opinion. There is no need to limit a forums thread to 1 post per person.
