Personally I disagree with the thanks system on a support site. I don't use it so I feel a little bad when I get a thanks.

If I thank someone I do it in words because I don't want it to be about button pressing I want them to know they added something to my thoughts and also I want to explain a little in what way.

But it is my choice. No one is going to make me push buttons. I do on a more debate type site where people are thick skinned but that is different.
