S. John Ross, the revered creator of Risus, recently posted submission guidelines for authors wanting to publish official Risus supplements. Since that time, I had been wondering when somebody would take a stab at it.
Well, evidently my waiting is nearing an end. Over at the Risus mailing list, S. John has hinted that at least one author's work has progressed to the playtest stage and that it has him "abuzz", "atwitter", and "vaguely agog". And apparently it involves specific historical costumes for our beloved LCBs (Little Cartoon Bastards - otherwise known as stick figures).
