title: create an eventreceiver for logging changes made by users in lists
body: <p>I'm working on a SharePoint publishing site and I want to "log" all the changes made by users in a SharePoint list. </p>
  
  <p>Some searches on the web guided me to the EventReceiver.
  But my EventReceiver must be generic and attached to all lists in the site collection. The "log list" has several columns like the name of the list in which the event occurred, the name of the modified item, its old value and its new value.</p>
  
  <p>Can someone guides me on how to achieve this?</p>
