[plt-scheme] PLT implementation of wiki?

Is there a wiki implemented in (PLT) scheme?
 
I found something called moshimoshi, but it doesn't appear to be active. I found another scheme wiki in a different version of scheme (Gauche), but would prefer PLT if I can find something. (Or even systems comparable in functionality to a wiki, if such exists in PLT).
 
Thanks for any info.
 
cheers,
skg
