It's easy, the smilies located to the right click "more" and you will see all the ones to choose from. I open up the entire window, (the "square" at the far right at the top of your screen). At anytime you would like to add a smilie to your post simply click on it and it will be added. Then simply close the window. You can add multiples at one time, just click on as many as you would like. The smilies at the bottom are added above your message. When you click preview they will show up.
Hope I made myself clear, and did not sound condescending. Don't hesitate to ask if you have any questions.
