I finally put the last monkey to bed, and will be updating the Urns of Infinity shortly, as well a new puzzle.

It has come to my attention that there may be a need for regular moderators in the Discussion Forums. If you have been a long time contributor and would like to volunteer, please contact me, either using the regular form or by posting into the "Ask the Minotaur" thread.

Thanks!
