Please remind me how to add EasySocial modules to the Dashboard page

I see that somehow I have turned the EasySocial dashboard page into one column with no sidebars. I am wanting to convert that back. Can you point me to instructions on how to modify this. I have been adding items to the module positions but they are not displaying. So, somehow I seem to have removed the positions.
