Hrm, I'd always imagined our characters living at their base, Teen Titan's esque. I mean, won't most of the action and interaction take place or be launched from there? Or were you intending to have everyone post about what they do during their own time, too? I guess that could be pretty interesting and lead to good character development. If it doesn't work out, you could always just have someone bring up the idea to move into the base later, would make much more sense than doing the reverse.
