Is there a way to track or record users entered taxonomy? Is there a way to track, flag, or record a users entered taxonomy even if perhaps they may have changed it (tagging). So basically I am trying to set up a list of all the taxonomy tags a user created. The thing these tags can be changed and manipulated by the user so I am wondering if the originals can still be added to my list after they may have changed to a new tag. For example, a user recording places of employment.
You may want to take a look at the Community Tags project.  We have used it on a few sites.  From the project page:


  The Module has three main features:
  1. Stores who tagged what and when.
  2. Allows for this information to be exposed with views.
  3. Adds an easy AJAX interface for tagging nodes without going to node/edit.
