Dear Mun

Here and here. More akin to a dressing room than a standard roleplay, with the same drop-in/drop-out, no-applications format. The premise, such as there is, is notes from characters to the "mun" (player).

This game provides examples of:

 * Breaking the Fourth Wall
 * Fourth Wall Mail Slot: An inversion--it's essentially a Fourth Wall Mail Pickup.
 * Insistent Terminology: The moderator keeps saying that this isn't a dressing room and that those who wish to use it to RP should go somewhere else, but absolutely no one listens.
 * Mega Crossover: As a place where characters from different panfandom RPs can and do interact, this manages to be a Mega Mega Crossover Crossover.
 * Rage Against the Author: About ninety percent of the posts are this.
