Well, for one it was both me and Michaela deciding, and also because, well, we felt that the others we did accept deserved it. Her SU was really only slightly longer than Jumbo's, and I guess it would look longer than Kazuki's, but he sent more to us over PM(so as to keep his history a secret, at least to the other RPers) and I also know how well Deep, Stingray, Jumbo, Zamorak, SIU, and Scarf Blade role-play, and James In Flames' SU was amazing. Besides that there's only Kazuki, whom did rather well on his SU.
I don't really like declining people, but SOMEONE has to be declined, and sadly ~Genevieve~ was one of them this time. She's always welcome to come back when a spot opens up. ;3
