Not quite sure what you mean. There's a smiley system built in, you just add the url to the smiley you want visible within it. There are also loads of extra smileys available in the Resources downloads.What smiley add ons does xenforo use?
I know xenforo uses more than what comes with the normal xenforo download
I think the poop one could be conveyed as being too negative (i maybe wrong) but it would be worthwhile adding the rest since it would save on tons of support imo.if there is a sprite in xf installation then I don't understand why not all of the smilies are included after installation?
