here's a few:
if you go into your "User CP" and select "Edit Options", way down at the very bottom under "Miscellaneous Options" is a scroll-box with three choices. choose "Enhanced Interface -- Full WYSIWYG Editing" and it'll allow you to easily drag photos/emoticons/etc into a post. so you could drag the emoticons from this post in to your own.
obviously not as easy as just clicking on a smiley but it's the next best step.
(i'd have put them all over here in this post, but apparently there's a limit of 4 images in any single post.)
