In the smilies we have icons for just about anything including a thumbsdown smilie, so why don't we have a thumbsup smilie? I know we have a thanks button but you can convey so much with a simple thumbsup within a reply to show you agree with what someone has posted. I also know that members can post their own smilies but I am too thick so would someone with more experience like to do it?
Maybe we could even run a little competition for people to post their original smilies?
