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)
'We should not congratulate someone on the success of their misdeeds, but on the contrary should endeavour to advise him or her to lead a more skilful and wholesome life. If such advice is ignored then we can only give up and let go' - Phra Panyapatipo
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.
