Suggestion: 'Thank you' button?

[LavoChain]

Tell me to go away if this would be too much work or a pain.

I was just wondering if a 'thanks' button would be at all possible on the forum. They use them on other forums that I'm on and they're a great way to either 'like' a post or thank a poster without posting again. I sometimes feel like I'm being pointless simply making a new post just to thank someone or acknowledge them. I think it would be good to have some other way of acknowledging people, to save being ignorant and ignoring them or boosting a board that may be dead.

Just a thought

P.S sorry if this has been asked before!
