Conquest of the Horde

My statistics as shown below are:
Has thanked: 1 time
Have thanks: 1 time

What does that mean? I have thanked 1 person before for a post I agreed with, and someone has thanked me for a post I have put?
If that is what it means, what is this for anyways?

That's exactly what it means. If you click the "Toplist" button that's next to the Logout button and the others, it'll show a list of the highest-thanked posts and threads.

Server News post detailing this!

Do the admins manually keep track of every single thanks a person gave or received? I don't quite get how the number id determined unless there is something you click on. I'm sure I've thanked people for their responses to posts, unless I am mistakened on what is considered thanks and what isn't...

There's a small button on every post with a thumbs up icon, that's how you thank people!
