Cut to the Chase Games are giving away "Mad Dave" Olson's WK0 Night of the Mad Kobold until the 16th of September. The adventure is aimed at six 1st-level adventurers and is written under Swords and Wizardry. Converting to Original or Classic D&D, or to Retroclones based on these systems won't be a problem, but I think Cut to the Chase are a little quick to say the module can be run under OSRIC. It can, but it will need some conversion along the way.
