[quote=Kestral]Basically you want someone to acknowledge you did something. I get that, but to call that common courtesy is silly. I mean, I join an RP to write collaboratively and interact through fiction; that in and of itself is my reward. Sure it's nice if I get a compliment, but that's not why I RP or submit a CS.[/quote]

No, not at all. I don't require or expect people to read my CSes. Even if they did or didn't I would still read every other player's because again I think it's common courtesy and simple nicety. If they've gone to the effort of writing it out, then as someone who may be playing and rping with them it's a simple, nice thing to read their input and work.
