We would like to extend the functionality of Sharepoint 2010 to improve the Social Networking Features.

We want to trace a SharePoint 2010 user events, whatever he/she performs on the site collection level.

Say:

• Uploading a document into the document library
• Adding an item into the list
• Adding a discussion or Replying to an existing discussion
• Uploading an image into the Image library
• Involved in any of the workflow activity
• Changing his social status
• Posting a Wiki /Blog
• Any changes in the calendar List
• Any changes in the Task List
• Setting/Modifing Alerts
• Any updates on the Announcement list
• Contacts update
• Colleagues added/removed
• How to achieve this?
