I suspect the problem might be that some of the smilies have the same name. I noticed this was the case at Buddhachat too.
Thanks, we'll look into it.
If you have asked me of the origination of unease, then I shall explain it to you in accordance with my understanding: Whatever various forms of unease there are in the world, They originate founded in encumbering accumulation. (Pārāyanavagga)
Exalted in mind, just open and clearly aware, the recluse trained in the ways of the sages: One who is such, calmed and ever mindful, He has no sorrows! -- Udana IV, 7
I corrected the problem. Some of the smilies had the same code as similar ones, as retrofuturist said. It should be all fixed now. Let me know if there are any more glitches, and any smilies you would like to add.
