My understanding of Sequential Art is that it is what is used in drawing for Graphic Novels. Emilee is continually writing her stories, which are variations of existing manga, and illustrating them. She is quite talented, and has had some of her art published in Newtype, a magazine for Anime enthusiasts.
She, Clare, and their friends hang out at deviantart.com. They do live-journaling and chat there, and post their art for all their friends to see.
