Alright, here's how things look for our currently scheduled matches.
I just added the one on the 22nd and added the people that said they could make it any time. If anything needs changing let me know.
I told the teams we're playing on the 17th and the 19th that as of now, we can only do 6v6, but if a few more people say that they can make it, I'll tell them otherwise.
Also, we can be "forced" to host all of these, I know stranded said he can reliably host 12, so it might be necessary for you to host on the 17th and 19th.
zen and tux said they might be able to host 20. Have either of you tested that yet?
