Hi Vince,

in SmallWiki this could be easily done by subclassing 
SWVisitorRendererHtml and overriding the method #acceptText: with 
something like:

	SWVisitorRendererHtmlSmiley>>acceptText: aText
| 		| stream |
		stream := aText text readStream.
		[ stream atEnd ] whileFalse: [
			html text: (stream upToAll: ':)').
			stream atEnd ifFalse: [
				html image: '/smileys/smile.gif'.
				html inputStream skip: 2 ] ]

I haven't tested the above code and it does only support one kind of 
smiley, but I'm sure that a more complete solution can be implemented 
within no time.

Cheers,
Lukas
