How do I get the faces to show in my post? Don't mean to sound stupid, but every time I tryall I get are the keyboard versions. I'd like to use them!!

There are two views you can have in the editor while composing your posts. In the standard editor, you will see the formatting codes as you type. In the rich text editor, most (but not all) formatting is visible. It isn't quite WYSIWIG, but it is close. To see exactly how your post will appear, click the "preview post" button. To switch between versions of the editor, click the button in the top right of the edit screen with the two curved arrows on it.
