Equestria in their private time. This is where you can be your OC or a background character or one of the Mane Six, but act out what you do in your free time! Maybe RD likes to write Daring Doo fanfictions? It seems to me this would be more a roleplay, but everypony has different opinions. Also no explicit stuff like swearing or r34, just whatever the character your roleplaying does in their free time.
I think this might belong in the character disscussion area rather than the role play area, at least that's what it seems like to me.
