That is a good Idea! Glad you made it public, too. Now I can thank people for posts that I enjoyed reading, see exactly which posts I have given a 'well-done' for, and which ones are still needing to be given a 'thank you' for, and all without cluttering up the threads!
I love being told thank you for such and such a post/thread, but would really prefer not to have a post made for no other purpose.
The reputation system solves this perfectly!
