Not until at least Sunday, when 13 gets back. We've worked out a couple of ideas for beginning plots, but honestly we could use some more time to work out the kinks. I don't want to set a set date for this to start (in case I'm wrong) but at the earliest it'd probably be Wednesday to give people time to finish up their characters, beginning plots, and for people to return from trips/feel better (I know our resident Index/Railgun expert is sick right now and definitely want to give her time to recover at least).
Will it be the same obscene wait before Reborn started? No, but you still have some time if you want to make more characters or work with people on making your own plots.
@EDIT: Terry, Sakurako can be the one from Tokuwadai that Hisagi knows if no one else volunteers. ^.^
