All patrons are eligible to vote on what map from the back catalog gets released at the beginning of May as part of the "Release The Kraken" milestone.
If you haven't voted yet (and the voting is pretty close between two of the maps, with a whopping 0.8% difference), head over to
http://goo.gl/forms/jiU73WMm2W and get your vote recorded. I'll release the map in question on May 1st or 2nd!
