I followed your instructions,and the right side of the post icons is blank,no more post icons. Down my post icons says this: You may choose an icon for your message from this list.
Please help me.
There should be a square box on the right side of your message after you click "go advanced" when typing a message. It will have like 12-15 emoticons in in and say "more" underneath. When you click it, you'll get a little pop up box with a list of all of them. Let me know if it doesn't work!
