You could be using some weird browser that doesn't support tables or javascript... though I'd really doubt it.
There's a link at the bottom the smilies table proclaiming : "Get More". If you seriously need tech support, tell us what you see, to the left of where you type your replies.
If you wish tell us a joke, tell us what you fell like seeing....
(on the other hand you could always quote other people whenever you need a smilie...
