Thank you, those are good tips!

I am getting nervous about it again as the organizers seem less and less organized the more I hear from them -- an email Sunday said that we would be asked to sign up for our preferred workshops this week, but I have not seen anything about that since-- and in another email, they asked for volunteers to do X and then two hours later said that it turns out they can't do X after all.

I think I have volunteer PTSD -- I worked with an incredibly poorly run organization earlier this year and now I'm worried this is going to turn into a four day nightmare as well. I need to just stop thinking this way!
