The mods have met in plenary session (which is pretty good considering we're 12000 miles apart!

) and have decided, much against our better judgement, that there will be a 2 week extension.
Thus the GB will end at midnight, local time wherever you are, on Friday June 14th.
In case that's confusing it means you can carry on building until 2359 hrs on the 14th, but have to stop within the next 60 seconds.
