You can sign up at any time, no matter what. If I don't get many sign-ups for a while, I'll start this role-play with even just one other person. Feel free to sign-up and jump in whenever (make sure I accept your sign-up first, of course!)
Oh, and please don't make reservations if you're not actually going to sign up.
Hey there, who else likes Kirby here?
I do (because you totally couldn't guess that).
You can sign up as many characters as you want! :)
We're all in Dreamland, just so you know. No space travel; we don't want this to get too complex.
