I find this important enough to make an announcement about it.
If you have not noticed, I have added two features: Kudos and Thanks
Donuts is something you can give a post, if they have done well, at the top right hand corner of the post you are donuting. This is to show which user is the most helpful around. Donut wisely.
Thanks is another thing to do, that is next to the quote button. This is an upgrade to a kudo, so only use this if a post is amazing and deserves more.
Remember, you are limited to how you use these, so you may run out one day.
