I am up for generally dickery in SM once it is going, and seeing as I spend a fair amount of my gaming time in FPS's I will probably want to spend a decent amount of time doing that in SC-PU.
But as its been said above here, it's a bit early for structure. If anything semi-organized chaos of people listing what times (and time zones) they will be expecting to play, so we can loosely form groups based on interest from there.
I for instance will in all likelihood be online Tue-Sat 8pm-10pm PST.
That is just a tentative time of course. Life will find a way... to be a dick and change my schedule.
