Kudos are points that are given to you from other members for
being helpful, or other reasons. You can earn kudos by posting helpful info, or posting pics in the gallery.
If you look below the word kudos, you will see the word donate. Just click that to donate some of your kudos to another. When you donate it will take kudos from your account.
Hope this helps.
