To the other questions:
WTA or PPSC. I actually don't care. However I stated WTA in the beginning, so unless everyone is ok with PPSC it should be WTA.
Points. Again, I don't care. I say let's make game one 250

and game two 25

?
Pauses: Most likely we'll need to pause for Christmas. For two weeks at best, maybe more, until everyone comes back :)
Phases: Any preferences? I generally like 24h, longer than this breaks up the dynamic of the game, you play a year in a week with the weekends dedicated to silent retreat and build phases, and one has to come up with a lot of useless chit-chat to not look suspiciously silent... or is that just me? :)
