It'd be 4E, its Mountain timezone, and whatever works for times is probably okay. But not Sundays.
as far as campaign length, i figured that'd be kind of dependent on players. i have a few over-arching ideas. and i can probably come up with some 1 shots too, so i guess it'll depend on how things go. ideally it'll go for a long while, and happen every other week or so, as i will probably need extra time at the start to build encounters and whatnot.
There's a thing called Mountain Time Zone? That's so cool :0. I should double check these things before I post. I live in GMT +2 so there's quite the time difference between us, but I can stay up all night if need be so I doubt that's going to be a problem ;)
I can most likely fit the game into my schedule regardless when it is, assuming something doesn't come up suddenly, but I'd prefer it wasn't on Wednesdays or Weekends, I usually have something else to do during those times, but I can see if I could squeeze it in...
As for length, I'll stick around as long as the campaign lasts so it's all up to the rest of you.
