Hopefully one day this will come back, and thanks to space for running it for so long.
I'd like to add that if you're still looking to get a dose of DOU goodness we still hold regular room tours in the
Smogon Doubles room when there's enough interest, and even if there isn't one, you can still ask for battles (as long as you aren't spamming), so be sure to take a look and join the room sometime!
