I'm not sure. I PM'd Rakki three days ago, with no responce from him yet, and I also checked to see when the last time he logged into his PokeCommunity account, and it's been since the middle of July for that one, so I clueless about why it's gone. The Doubles League he was running is gone, as well.
I told Rakki to tell anyone from The Zodiacs that needed a place to post until it's figured out that you can post in 7DS' thread freely. You do not have to become a member to do so, however, if Rakki did delete the clan for whatever reason, and you are looking for a new clan, we would have a place for you there.
