title: codeigniter - what if I don't have any model?
body: <p>It's the first time I'm using an PHP framework and I have a question regarding this design pattern.</p>
  
  <p>Let's say I'm trying to build an php app that has a contact us page (which will ask for the name, email address comment etc and once submitted it will simply use the mail function to send an email to the admin). I know what my view is gonna be, I will also use a controller to render the view, but what should be my model? I'm not going to load anything from the database or save anything to the database. So in this case should I skip the model?</p>
