I saw your post here—I'm replying by Wall Post because it should send you an email, whereas Discussions don't. To answer your questions (here's the Categorization Policy to reference as we go along):
 * 1) User-based categories are not only allowed, but encouraged. The proper syntax is "Category:Articles by [username]".  For example, mine is Category:Articles by Sakaros.
 * 2) Categories by fan-fiction series is sort of a gray area. For example, "Characters in the Untitled New Sith Wars series" would basically be a subcategory of "Characters by Sakaros", which is not permitted.  On the other hand, Category:Members of the Order of Keltrayu is totally okay; even though the Order of Keltrayu is one of my creations, the category organizes things in-universe, which is the critical distinction.

The Categorization Policy, while not quite the Image Policy, is still a little dense at first glance, so if you have any more questions, please feel free to ask and I'll try to clarify.
