unable to fine link for unkudos message

Hi,

Three scenarios, not sure what you are asking for:

1. Remove your own kudo given to a content item: Select "Revoke My Kudos" from the item's options menu
2. You are moderator and want to remove all kudos from a content item: Select "Turn off and hide Kudos" from the options menu (Although I'm not 100% sure this actually removes the kudos functionally and within the metrics/popularity calculation. It looks like it hides hte UI only)
3. You are moderator and want to remove all kudos a user has given: Open the user's profile page and follow the link "Remove All Kudos Given by this User" from the "Moderator controls"

Hope this helps
