Have masternodes started receiving payment yet, or is that part of the May 25th fork?

I'm really digging this coin so far.  Difficulty seems to be about as consistent as a roller coaster, but it seems to adjust reasonably quickly in response to giant changes in net hashrate.

I did run into a problem with my pool of choice...  Does anyone happen to know how to contact the folks running the show over @ pool.darkcoin.io?  I've made quite a few attempts to contact them using the Contact tab of the pool website, but I haven't had any luck getting a reply.
