I think the worst problem I have is that, I want to have a Session 0. But, two people can't make it (out of 6). Given that it's a 'once every two week' thing because people have stupid scheduling issues, I just don't want to skip. It's very frustrating.
If your players have Internet access, maybe session 0 can be done over a message board or mailing list over a week or two. You throw one idea, read the various responses, and move on from there. Think of it as the company memo.
