I would like to commend the person who had the idea to put the little quick "thank you" thing at the bottom of the posts.
I have used it several times when I greatly appreciate a post and am rushing and don't have the time to type out something.
It also could be used if it is a sensitive subject and you really don't want to elaborate further.
I appreciate the opportunity to thank folks who have been a help to me. Often times I can tell folks have put a lot of thought/time into a post and often times their efforts have been beneficial.

Wishing everyone a Very Happy...Healthy New Year!
