So much blog blove lately!
Aeryk and Enron, it doesn't matter whether you create new guys or keep using the old ones or a mix. It's fine to start at 2nd level and making a 2nd level guy is as easy as creating a 1st level one (make a guy, make the stat adjustments, pick a utility power and a feat, done!).
I was figuring we'd spend an hour or so making guys and then play until the Doc has to leave, but if you can get it done sooner, all the better! I'm basically just running a mini adventure or two so it will all work out either way.
It's gonna be fun! Unless we hate it and never speak again. That would be sad :[
