Sub sub-folders not working in controllers

So you have 2 frontend controllers : store and forums. I guess you are going to integrate the collections in your store?

For the admin you create a directory admin and in there you create the controllers store, forum, users.
In the store controller you create methods to do all the actions for the products.
In the forum controller you create methods to do all the actions for the forum
and the users controller has all the methods for the collections, profiles, wishlists, ...

I think you are not going to end up with too much methods in a controller. The actions adding and deleting can be in one method and you identify the action using the button name.
