How to thank people for their posts?
 

I feel silly asking this but I cannot figure out how to thank people for a post, can anyone help me out?

Also wondering this if someone could respond.

Maybe there's a post limit? Everytime I click a name on a thanked post, they seem to have a ton of posts. Usually on vbulletin forums there's a little star under all the posters information where you can add rep.

You have to have 10 posts. Once you do, there is a button on each post.
