It’s a good idea to get some images for the profile & background banner, to personalize this place. The Discussions Guidelines, located at /d/g, also need to be personalized. I can help with selecting images if needed, & I can suggest specific Guidelines that I have found helpful if anyone wants, or link people to the Guidelines that other larger, successful Wikis have used to great effect.
Those are actually secondary however. What’s most important is Discussions Categories; at least five are usually good, to help organize content in the same way Forum Boards do. A Category for each book, or perhaps instead for Characters, Magic, Theories, & Places would be good. Either way, a fifth category dedicated to Wiki-Improvement would also be good. In the end the decision falls to the Admins however, these are just suggestions.
