where's all the comment go???

This is a problem that I really need to take care of because I want to start doing it too. The thing is... I have to make a forum topic for every manga, video and game. That's over 800 things :(

Isn't there some way to rig a comment system like that on the main page updates, or is that a totally different system?

or in manga/vid/game section in fourms make a feedback category so people can title the gn and comment on it
