If you love vintage chapbooks and/or classic weird stories, how could you not sign up for the Miskatonic Literary Society? Every few months a lovingly printed and packaged masterpiece shows up, along with some period-appropriate extras - decorations, props, etc. It has been a great excuse to revisit old favorites of short horror (and in some cases, to find new ones!) I'll definitely keep signing up for these for as long as HPHLS sees fit to keep doing them.
