Red_massa was suggesting we make the topic/board now. When you make a thread on the Roleplay Boards (Free/Casual/Advanced/Nation/1x1, Not Interest Checks or Other Boards), it makes IC and OOC Tabs so that the group can talk Out of Character in one tab, and In Character to start the Roleplay.
But since this is 18+ we'll need to make two Private Message Conversations (One of IC, one for OOC) for that and we need to wait till we're sure we have everyone because there's no way to add people after we make it.
Unless someone has a good suggestion for outside this forum.
