Thanks to my semi-activity, I can see newer wikis evolving and changing, gaining new and shinier features. For example, many wikis now have pages with multiple tabs. My current project will be figuring out how to split pages into tabs - I think it's the key to solving our problem with a Hellsing character's anime version vs. their manga/OVA version.
But if any of you, the users, have any suggestions on how to do this, feel free to speak up! Reverse-engineering code is hard!
