title: Saving extra data with an order in Magento
body: <p>I have to add a column to the orders page which means adding a column to <code>sales_flat_order_grid</code>. Both of those are possible however I don't know how to add a value so that it gets saved in my new column.</p>
  
  <p>Do I have to register a new attribute too?<br>
  The value is not present in the quote so I guess I don't need to register under <code>config/global/fieldsets/sales_convert_quote</code> since the value isn't there to be converted.</p>
  
  <p>Using Magento Enterprise 1.8.</p>
