Names on Rescreatu must be unique, meaning that each name can only exist once on the site (there are a few glitch exceptions). The name Autumnal is already taken but have a play around and see what other pretty names you can come up with :) The box where you write the name will be red if a name is taken and will turn green if it's free.

 Once you've been on the site a while and built up an account you'll be able to purchase names off other users ^.^
