Now before you close yourself to the idea, hear me out. Some roleplays have multiple threads and some even base themselves on the livelihood of the many threads that are linked to their roleplay, but it looks awfully cluttered when all of them separately flow in the abyss of the other roleplay threads within the board.
My proposition is that once a roleplay becomes successful enough, it obtains its own childboard where they can create as many threads as they deem needed without it looking like a complete mess, that way, everything is in one place and looks neat and tidy. Plus it would give people something to shoot for.
Just a suggestion though.
