Application Structure

[eluser]M Moeen uddin[/eluser]
I m making an application, It has several feature, like blog, forum, bulletin board, Poll etc etc...

Now, if i make a controller for each, and a controller to interact or load all of the model, this will be confusing or not good way? or not?.

Please Tell me how to structure the application efficiently in CI.
