Thanks for the offer, but not being up 27/7 would make it too hard to attract enough people. I'd gladly work with someone interested in hosting it anytime, but I probably won't actively look for them until sometime near next summer as I'll have a lot more free time to make it work). I'll be sure to let you know when that happens ;)
This whole thing has been put on hold until I can find someone that can host it, as my new internet provider doesn't allow game servers.
As for inaccurate sleep moves, the goal being to stay as close as possible to the standard metagame, I don't want to turn non-viable moves into good options and potentially break balance. Giving Blissey a Yawn clone would be a pretty big deal ;)
