Hi Hyubie, I'm glad you've found it. Here's the thread that gives the information about the "Thanks Button" which is also in this Help and Feedback forum. This is the best forum to look for answers as to how the site works and if you can't find them, post a question.
Thanks again, BBW. Somehow I missed that page. I looked through the FAQs, especially about posting replies and messages, but the info was not there. I even tried the search function. I didn't get this page though (which does look like a header page - now I know not to skip them ).
