HAHA. They are points that you earn by posting messages and topics. For instance, right now you have 41 Kudos. Everytime you make a post you get 1 Kudo. Everytime you make a topic, you get 2 Kudos (I believe). People can donate Kudos to each other for giving them advice or for whatever reason. You just click on the donate button (it is below your name under Kudos) and enter in however many kudos you want to give. For instance, I just gave you 10 Kudos so you went up to 51. You can not give yourself Kudos. To give others Kudos you click on the donate button under their name. Get it?
