Do you mean when do we (the RPers) start or what is the timeframe for the characters?

Players:

There were a few other people who expressed interest, so we might still get another character or two.
[@Pathfinder], [@Thundercrash], [@Weird Tales], [@rocketrobie2], Still interested?

Characters:

The first post says that the new supers' first patrol will be tomorrow (in world), so I'm guessing they've at least begun their training with Frozone. Perhaps they've been living together for a week or so? That's long enough that we don't have to RP the introductions and get on with babysitting, but not have the characters too familiar with each other, and able to grow quickly in their relationships.
